[Q] SPDIF audio passthrough possibilities for RPi? - Raspberry Pi Q&A, Help & Troubleshooting

Have no HDMI in my house. I can convert HDMI to DVI and run it into monitors, but that leaves me with no digital audio. The RPI is weak enough that I would rather offload the audio rendering to a receiver. What inexpensive and cpu efficient ways have you found to get optical or coax spdif / toslink passthrough?

You could check out the HiFI Berry:
http://www.hifiberry.com/
There are USB DACs as well.

More than I was expecting to pay, but it's an option that I did not know was available. I've used DACs for audio recordings. Does anyone know if there is considerably less cpu overhead for those vs the onboard analog out and some that have been tested with XBMC Rpi distros?

The HiFiBerry Digi is an S/PDIF output (can be found on the same web site). The HiFiBerry DAC has been tested with Raspbmc. The support in the current version still does not work, but the january release of Raspbmc should fix this. I would expect that the HiFiBerry Digi will also be supported in Raspbmc soon (but not in the january release).
I don't have did any tests with the onboard sound, but with the HiFiBerry DAC there is only a minimal CPU load, as data transfer to the sound card is mostly done via DMA.
Best regards

I'd probably go with the hifiberry AS it just fits and isn't too expensive. There are pretty cheap bay China USB China sound cards, they work ootb with raspbian. Or you go full high end with the Buffalo DAC which is what i did. I know, it's just Voodoo...

Hi, I just stumbled upon this old post. Anyway, here's how I resolved the same problem:
Buy HDMI to HDMI + SPDIF + Analog converter from eBay, plug it in and you're good to go.
I'm not allowed to post links so: search for "hdmi spdif", select order by price+P&P: lowest first. It' the one like on the image.
It's true passthrough (Dolby, DTS), and you don't need any kernel modules, and you get to keep it or use it elsewhere, unlike with HiFiBerry.
...and you get a free set of knives :laugh:
here are the flags from config.txt:
config_hdmi_boost=4
hdmi_drive=2 (I think this one is important)

HDMI dock review

This is a bad and hardly structured review with a focus mainly on video playback. This is not a full review, and there's more things I want to test (and probably info I will post) for the future. It is also 4 AM, so don't expect any literary gymnastics.
So, I've had the (Euro) HDMI dock for a few weeks now (as well as the black leather sleeve, which is nice) but hadn't really gotten around to testing it. Primarily because I hadn't gotten around getting a mini-to-normal HDMI cable - yes the dock has a mini-HDMI output. The cable in question is commonly known as an HDMI "A<->C" cable with male ends on both sides.
Let's get the details you all know already out of the way. We're talking about the ECR-D980, more info here.
The dock itself comes packaged with nothing. No extra USB cable, no HDMI cable (or even converter plug), nothing. Keep in mind that these up the total cost of ownership for the dock quite a bit. I got the dock for about 29 euro, add about 20 euro total before you have a second SGT USB cable and a mini-to-normal HDMI cable. So that's 50 euro or about $70 US minimum cost at the time of writing, significantly more if you don't search a bit to find the cheapest deals. You don't strictly need the extra USB cable, but it becomes annoying in most setups if you don't have it - you'd be switching the cables location a lot.
The dock itself feels like a solid piece of equipment, much like the Tab itself. It features a 3.5mm audio out, mini-HDMI out, and 30-pin Samsung "PDMI" USB / power connector (the same connector on the Tab itself).
I started out testing at a friend two weeks ago, using his Sony soundsystem (several HDMI ins & outs) and his 42" high-end-4-years-ago Philips LCD. We were however completely unable to get it to work. Having no clue which component the problem was, we gave up after a bit. Note that his LCD doesn't do 1080p, but max 1080i (at time of purchase, even 1080i was rare). So I borrowed his cable, and today I tried it (with his A-C cable) in my home, on my Samsung 6-series 37" LCD that does do 1080p, without any special soundsystem. Note again that I used a converting cable, not an A-C converter plug. I know people have reported problems using those.
As soon as I plugged everything in, I immediately had display on my screen. We still don't know what the issue was at my friend's house, but keep in mind that it may be a requirement that the display device supports 1080p. The signal received by the TV was 1080p30. I think this is the maximum the device will do, as my TV does support both 1080p50 and 1080p60 as well (and I regularly use both those modes).
Immediate snags:
(1) First, the dock needs to be connected (via the USB cable) to a power, or HDMI will not work. I actually used an old HTC adapter instead of the Samsung one, that delivers 1a instead of 2a, and that worked fine. Connecting it to a computer USB port (0.5a) reportedly does not work, but I have not tested this myself (yet).
(2) Second, the Samsung USB cable you got with your Tab is really short, using an extender cable is almost certainly necessary for most situations.
(3) Third, the 3.5mm audio out does NOT work while HDMI is connected (reported by others, not tested myself)
(4) Last, the backlight will NEVER go off when connected over HDMI. Not even using the power button.
So, when you have it all connected, you will see one of two things: a really narrow output of your portrait screen, or a screen-filling output of your landscape screen. I advise everyone to put the device in landscape mode and enabling the orientation lock before connecting. Note that the HDMI dock is also a really handy standard for landscape mode!
When in the normal Android UI, you can clearly see the artifacts of upscaling. You'll see whatever happens on the Tab on the TV as well, scaled up (and not using a good resampler). The Android UI does NOT suddenly see a FullHD screen (as I expected, but some may be surprised).
However, some applications that go full-screen do see and use the FullHD resolution. I have not extensively tested this on many applications. For example, the YouTube app appears to see FullHD, but I can not be certain. The stock Samsung video player does see and use the FullHD resolution, as far as I can make out.
I have tested playback of the following videos, in the stock video player:
(1) Iron_Man_2-DivXPlusHD.mkv - 81mb, 2:30, CCV1 1920x800 23.98fps, AAC 48000Hz stereo, 4.4mbps
(2) Cowboys & Aliens - Trailer.mp4 - 174mb, 2:31, CCV1 1920x816 23.98fps, AAC 48000Hz stereo, 9.2mbps
(3) v.2009.s02e03.720p.hdtv.x264-ctu.mkv - 1118mb, 41:22, CCV1 1280x720 23.98fps, Dolby AC3 48000Hz 6ch, 3.6mbps
(4) the.mentalist.s03e12.720p.hdtv.x264-ctu.mkv - 1119mb, 41:48, CCV1 1280x720 23.98fps, Dolby AC3 48000Hz 6ch, 3.6mbps
These four videos all played fine, with audio and everything. V even had subtitles, and those worked well. However I must note that the button to disable subtitles is disabled while outputting to HDMI. Not sure what that is about. DTS is still on my to-test list, but I'll get around to that when we get the setup working on my friend's soundssystem, where I can also test whether or not the output is more than stereo or always downsampled to 2-channel.
The video output is pretty good, but not without buts.
(1) First, as stated before, the backlight on the Tab will not go off no matter what you do, and you will see one of the first frames of the video as a still on the Tab. You can however still use much of the videoplayer UI (which is suddenly slightly different: amongst other things options like brightness and scaling disappear), and that UI only appears on the Tab, NOT on the TV. Now if only I could control that UI, over Wi-Fi, with my SGS ... (might be possible through DLNA, btw, a nice test for the future)
(2) When you look closely at the image produced, you will see that the postprocessing is not quite up to par to the quality you get from CoreAVC or even ffmpeg on a laptop or HTPC or whatnot. The difference does really seem to be postprocessing though, not bad decoding or scaling.
(3) There is some shift in framespeed. Not traditional suttering you might see when the player cannot decode fast enough, though, the speed seems to be fine. I think this has to do with the fact that first the Tab has to scale 24fps to 30fps, which is probably done with some pulldown scheme, and then my TV has to scale that to 100hz, again with some pulldown scheme. I'm sure the videophiles amongst you will understand what I am talking about, even if the jargon is not correct. If you're not following, you are probably someone who wouldn't even notice it. Also note that I have all video-enhancing features on the TV itself turned off (as always). Enabling the 100hz motion interpolation mode makes the issue mostly disappear, but I really hate the "homevideo" effect you get when doing that. All in all, when watching a 40 minute show, you don't really notice it anymore after a few minutes, but if you're like me you know it's there and see it. If it were 1080p25 instead of 1080p30, the issue would probably not exist.
All in all, it does look good and works pretty well. Unfortunately, though most of these individual issues are small, together they are big enough to prevent this from being more than a casual playback device. It comes close, but not close enough to being a home-theater device. However, who knows maybe XBMC can be ported and we'll get past a number of these problems.
I won't make any claims as to whether the HDMI dock is worth the money or not. You know the price, and you have a bit of information here, and more in other reviews online. You have to decide for yourself it it's worth it. Hope this is helpful and/or interesting to someone.
For me the dock was totally worth it. The framespeed issue you describe is definitely there, but I do not notice that unless I am consciously looking for it. I have watched a lot of movies quite comfortably using the dock on Full HD TV.
And yes, if TV is not 1080p, for example just HD Ready and not Full HD, the video output is not HD at all. I think it's the same as Tab's screen: 1024x600.
"Connecting it to a computer USB port (0.5a) reportedly does not work, but I have not tested this myself (yet). "
USB from my computer (Kies drivers installed) works fine with the Dock. I have an HDMI capable computer monitor and this also works fine with the dock.
Thanks for the review!

Have you tried movies with DTS ? And on a surroundl soundsystem ? If so, can you share the details ?
Re: 1080p, you are saying even if the TV does not support 1080p, you do still get output ? Would mean that 1080i is not the problem on my friends' system, as we got no output at all.

Worked out of the box for me, through HDMI. Haven't tried 3.5mm jack. Have heard that complaint before though.
Nice review its a bit dissapointing for me that they chose the mini HDMI standard as there is plenty of space to have included a normal size plug.
Maybe I'm just annoyed because I have HDMI cables laying around but now need to buy a mini HDMI cable

100% agree
YouTube is great when you're docked. You can flip through videos and playlists on the tab while a YouTube clip continues to pay fullscreen on your TV - nice! It's a shame you can't play HD though.
I stripped the DRM off all the free movies that came with my Tab so I can play them directly through the dock. Inception looks great! You're right though, post-processing looks a little rough at times.
The dock is pretty overpriced for what you get but I'm happy with it all-in-all. If it came with a mini HDMI cable it would be perfect.
are you using a stock rom or custom rom? wondering if that will matter in regards to dock performance, i am on the rotohammer jme v4 and love how fast it is compared to the stock roms.
thanks for the notes/review!

My projector is 1024x768 and the dock work well with it, so 1080p is not necessary for it to work, and as a power source I use an external battery rated 500mh, so I guess a computer usb port should be able to power it.
My problem is that my projector doesn't have an audio out jack, and when the hdmi cable is connected all the audio port of the tab get disabled, INCLUDING bluetooth audio. This is why I now use this dock as an overpriced charging dock

Just an FYI. $37 Shipped.
FYI, I got this 6 foot long Samsung sync/charge cable for only $8 (with shipping) that is a great companion for the Dock because the stock Samsung cables are way too short.

As metioned in the first posting of this thread, unfortunately you cannot turn off the screen on the Tab when it's in the doc. When watching video's the first frame of the video stays visibile on the Tab the entire time. When your not watching videos the displays on the Tab and your TV are mirrored.
I buy the HDMI station dock and I find it no really good!
A HD photo is not so nice on the LCD, it ok buy when you see then at the real resolution with the camera, it's bad!
The only way that I can have good resolution is when i plug the tab into the PS3 like a hard drive annd the I see the same photos like they are and my videos arein real 720P or 1080P
I will returned it and wait for a new model or plug into my PS3
I just picked one of these up and was a bit disappointed with the video quality too. Videos looks great in HD on the Tab but jaggy and average quality on the TV - no better than a DVD really.
I bought one so I could connect it to the TV in my hotel room when I go on Holiday soon. Is it true that if you get no audio over HDMI, you can't use the line out at the same time? I was going to take some small speakers just in case the TV in the hotel didn't support audio (should be fine, think they're Samsung 32" LCD TVs).
I'm a bit surprised there's no settings you can tweak on the Tab other than PAL or NTSC to correct the overscan and advise on resolution and FPS.
Surprised about the quality, I loaded a webpage up in Xscope and could hardly read it on the TV, very poor. I genuinely thought it would be near HD. I could just take my 13.3" Laptop with HDMI out but that's 2.5KG.
At least I'll get lots of films on the Tab as there's no point putting HD ones on there if they don't look HD on the big screen. What an oxymoron that they look better on the Tab screen!

HDMI to VG cable

I got myself the first HDMI to VGA adapter I could find, and once I got all the parts for my RPi connected, I found that the display on my VGA monitor is worse than crappy. Whether I use a plain terminal, the XDisplay of RaspBian, or the latest XBMC-based distro, I could not get anything useable. Until I patiently played with the XBMC and changed the actual display resolution to 640*480. Not very impressive, but it is stable.
I need to know how to change such setting for, say , RaspBian.
I want to find a *GOOD* HDMI to VGA cable that will actually work with the RPi.
Thanks

How much memory do you have allocated for the GPU?
I was looking around and here's a test someone done (full source here):
64 MB = No-HD Playback (Black screen)
80 MB = No-HD Playback (Black screen)
82 MB = HD Partially working (Some HD movies dont play)
84 MB = HD Partially working (Some HD movies dont play)
88 MB = HD Playback (seems to lag a bit)
90 MB = HD Playback <- Seems to be good. I will test it a bit longer.
92 MB = Perfectly working
96 MB = Perfectly working

The user mentioned that the optimal memory split for decent HD output was 100MB.
Don't forget that VGA is an analog signal, so make sure you don't have anthing generating a lot of interference.
If the cable you bought is of low quality, it may be and easy subject to interference.
Will try your configs

That may sound like a stupid question, but where can I change this information ? For sure I will try this before getting another cable like that, to see whether this makes a difference. As for the interference, this is also something that I want to check, like installing the minimum cabling on a clean table to see whether this makes a difference.
Thanks
If you're using any of the raspbian based distros, just ssh into it and edit /boot/config.txt using nano:
Code:
sudo nano /boot/config.txt
and search for gpu_mem and edit it.
If you're not on a raspbian based distro, shut down the pi, put the SD card in your computer and edit the config.txt as mentioned above.
[SOLVED] HDMI to VGA adapter cable

HDMI Output to 720p

Hi @all,
I've a problem with Chromecast. My setup is that I'm using an Onkyo receiver which has plenty of HDMI slots. Since I've no TV I've connected a monitor to the Onkyo. Unfortunately the monitor works at best in 720p (I've also attached a PS3 to the system where I'm also using 720p)...
So my question is, can I force Chromecast to output its HDMI signal in 720p. I don't have any image at the moment, with the exception during booting... (I see the Chrome Logo).
Any ideas????

720p is the highest and I believe the default that chromecast outputs at. You can change to 720p high or low bitrate, or 480p via the chrome browser extension.Sorry I was thinking about tab casting when I read the OP.

That's false. That setting is only for the resolution of the tab-casting. Not the output of the Chromecast. Chromecast outputs a 1080p signal. (https://play.google.com/store/devices/details?id=chromecast). I beleive it even upscales lower resolution content to 1080 but I can't confirm on my current setup.

Thank you so far.... yes, it is about the signal what's coming out of the chromecast not about casting! I definitely need 720p and I hope somebody can tell me how to force this device to do this.... Normally you could do this on any device (PCs, PS3, Xbox, Ouya...).
I'm really open to any advice.
Hi, I'm wondering if you found any answer to forcing(?) chromecast to a certain resolution. I'm wondering if the chipset inside the stick is capable of outputting anything other than 1080P? In my case I have to have 480P or 1080i (my TV is too old that it doesn't even accept 720P <LOL>). I know the Roku3 won't output anything lower than 720P so I'm wondering what the chip inside chromecast is capable & if there are ways to turn the switches on/off?
I'm still searching for a solution... none found yet.
What I figured out is that Chromecast can detect what the device can display at maximum. There is a standard to this...
But in my case (the AV receiver which accepts full resolution but the display not) I can't force it to do this... I submitted a feature request at Google help... I also read that people claim Google are very much interested in getting feedback... so I did what I can do.
So for now my Chromecast is just an Audio Stream adapter... but a quite good one so net completely useless for me
Thank you for the heads-up and I'm glad you are getting use out of it
Been looking around and found some info on the variant of SoC that is in the stick (from Marvell) as that thread suggested the info on Marvell site is thin and nothing about resolution. I sent an inquiry to their sales support but since I'm not looking to buy a lot of 10k of those SoC on the pallet so I'm not holding my breath for an answer. Also the thread said that it is not quite the same SoC so they were suspecting a neutered on customized for Google.

I have a similar problem, as I'm trying to run my Chromecast on a non-TV.
Short of Google giving options (which would be GREAT - most HDMI sources allow selecting what resolution gets sent), you could use an in-line EDID "injector" like Gefen HDMI Detective. They also have a DVI version of it called DVI Detective.
EDIT: Another option may be the Dr HDMI
In your case I would set the HDMI Detective to report that it only supports 480P and 720P resolutions and put it after your receiver (between receiver and monitor), so all your devices see proper progressive-only EDID.
Alternatively you could try to see if you can reprogram your monitor's EDID (via something like Powerstrip), though that's significantly more dangerous especially if you're a novice.

The Gefen is $129 and the Dr. HDMI is $399!
He'd be better off buying a new Monitor.
Dr. HDMI is only $99 (full boat HDfury3 is $399, Dr. HDMI is down past). But I agree, if money is to be thrown at the problem it's poetically better spent on a new monitor, unless you have something special.

OK, thanks for the correction. I clicked the buy now button and it showed up as $399, and I thought somethings wrong here.
OP, What monitor do you have? Does it not show any picture or is the picture quality just not good?
I recently did a search for best TV under $500 and their are some decent options for the money. My parents just picked up a 32" LCD TV from Costco on clearance for $180. It a Sceptre and 720p, but looks good and can handle a 1080p feed. It was on clearence, so might be hard to find at that price, but you can get a decent TV on the cheap with a little legwork.
Good luck.
FWIW as a test I have my Chromecast running to a Planar 1024x768 VGA monitor through a HDfury2.
The Planar says it's getting a 1280x720 signal, and I can tell from the green tint that it's receiving YPbPr (aka YUV).
So Chromecast definitely can output 720p if it thinks that's all the monitor can accept.
and I meant "probably" not "poetically" heh
any news?? I have a 720p projector connected to the onkyo. The chromecast doesn´t appear...

If you wall power Chromecast and boot it directly connected to the projector with the projector on, do you get picture?

When the screen says "starting...." I can see the picture well, I guess its on 720p, then it appears chromecast logo blurry and then a red noise digital noise screen.
I guess I need to change chromecast output resolution...

IIRC the boot screen is 480p.
This could be a failure of resolution negotiation (projector tells Chromecast it supports a resolution it can't handle) or missing/broken HDCP support on the projector.
Unfortunately you can't force Chromecast to a specific resolution so you'd have to control the reported supported resolutions with Dr. HDMI or similar that I mentioned earlier in the thread.
Is the digital noise blocky or more like fine random colored pixels?

The digital noise are red vertical lines at the screen, if I press the home button on my onkyo remote it changes to the casted image in 4 squares disorganized...
I find dr HDMI very expensive and I don´t think google will solve this issue. Maybe scene will do it eventually.
Well now I have a music streamer hehe, maybe I'll buy an fire tv or an apple tv...
Thanks a lot!

Interesting. Definitely sounds like your projector doesn't like what Chromecast is sending, maybe it doesn't like 1080p. Regardless, considering the cost of Chromecast I would just use it on another display or gift it to someone else and go with a more "full" player.

External DAC

Does someone tried an external dac on the G2? Does it work? Every DAC is compatible? I ask this because I have to buy an USB DAC for other purposes and, before buying, I want to choose one (if exist) that can be compatible with g2
You'll need to provide more details. Are you trying to OTG connect a DAC? If so, it probably won't work. Those not intended for Android use will not contain drivers for Android phones.
If you're looking to buy a NuForce Icon or FiiO E18, those will work because the G2 supports OTG, and the majority of custom ROMs retain that functionality as well.
So just post what DAC you're looking to buy. You're got every reason to be forthcoming. There's no way to tell without knowing the specific model DAC. If it's intended for Android use (i.e. the manufacturer advertised it as compatible) then it should work.
There quite a few that work with both nexus 7 ...so i wouldnt thinkg it being g2 would matter as long as its comptatible with other android over otg should work for g2 ..... Im getting a fiio e17 or e18 soon.

I don't have a dac but I need to buy one to be used with my hifi. I don't have choose a specific one and I ask here if there is someone that tried and get a dac working on g2.
Edit:
I have a usb headset, the corsair vengeance. That is not a dac but act like an external sound card. I connected it with usb otg cable and get the sound, but only the music played throught 'usb audio player pro' trial version. Is possible to get all the system soud directed to the external sound card/dac?

That means that we need modified kernel?
I have an fiio E17. It works with the G2 but i have clicks sometimes. For more than 16/48 I need USB Audio Player.
Hifimediy Sabre Asynchronous here, on CloudyG3 with the included kernel. Works fine, clicks sometimes when I start playback.
Got rid of clicks with the following additions to build.prop, normally used for Viper4Audio:
lpa.decode=false
lpa.releaselock=false
lpa.use-stagefright=false
tunnel.decode=false
Edit: False alarm unfortunately. But I have much less of them.
although this is a G2 FOrum I have a G3...
was looking for some answer to find out how to get rid of all the clicking or pops with an Asynchronous DAC/AMP. I have a HRT Microstreamer.
Anyway to fix or we all waiting for L?
Here dorimanx dev made a kernel that supports audio out to every usb device, so now every dac or usb soundcard are supported.

And here no lags or microshutters.
NuForce uDac 2 works well. Tested also cheap Beyerdynamic's USB soundcard and played too.

I can confirm the newest dorimanx kernels support precise streaming, limited to 16/48 by Android of course.

Raspberry Pi based HDMI(1080/4k) capture solution?

Hello!
I was wondering about the feasibility of having an HD capture setup using Raspberry Pi. Is there any boards that we can host on Raspberry Pi 3 which can capture clear HDMI signals?
Basically I am looking at a cheaper solution to capture multiple HDMI sources (1080p or 4k) using individual Raspberry Pi modules per each (or 2) signals. By this, my aim is to avoid using expensive multi-input cpature cards and a PC to capture.
Any inputs highly appreciated
Thanks!

Hi
What about HUBPiWi with three USB and a wifi which can be used with Raspberry Pi0 or 1.3. Have anybody used it or bought it please let me know
Most HDMI capture adapters require USB 3.0, which none of the released Pi's have. Even if this was feasible, once you start adding up the cost of the Pi's and USB capture cards, you quickly start to approach the cost of lower-end professional units/a dedicated PC.
If you're using this to do production work, I'd recommend looking into a dedicated solution like a Tricaster Mini or a Blackmagic ATEM Production Studio 4k. I'm not sure if it'll record multiple streams simultaneously, as it's more for live productions. I used to have the 1080p version of the ATEM. You could only record the output channel via USB, but it worked good as a production-level switcher.
Trust me...I've went down this same route in an effort to save on equipment for doing production-quality podcasts. In the end, I wound up going with multiple 1080p webcams w/ multiple USB PCIe cards (so I could do 2 cameras per bus), XSplit Producer and only use HDMI capture when absolutely necessary.
