Any chance to add digital output to Chromecast? - Google Chromecast

Hi All,
I was wondering if anyone who is familiar with the internals of Chromecast (1 or 2) can tell whether it would be theoretically possible to add digital output to it? I mean, to have Toslink or Coax digital output?
I know that there is Chromecast Audio that has optical out, but I would like to have Chromecast connected to my HiFi and HDMI connected to LCD display/projector. I would need to use HDMI audio extractor to do this - but I don't like this idea (another Chinese dongle to just extract the audio...) - since Chromecast Audio can do it (and from what I know, they share the same SoC to some extend) then maybe with a little bit of hackery and soldering the Chromecast could output the audio signal, too?
Disclaimer, I know this is probably not so easy and probably not economically reasonable - just a theoretical question.
Thanks

Suggestion
I have read your question and a part of the answer already contained in your question. As you said, You know it's not so easy and economically reasonable but yes according to my little bit research it's possible to add the digital output to Chromecast. This only can do if you're technically sound because of a lot technical issue which you need to understand and then follow the proper instruction to make this connection more effective.
As you know to connect to Chromecast is easy as compare to add the digital output to Chromecast. If you actually want to add then PM me, i try to help you to do this task successfully.

Audio Extractor for $ OR Is it possible ROOT for simultaneous cast?

My friend from South Korea sent me an early birthday gift and low and behold it was a cool Chromecast key :victory::laugh: WOW THANKS but... I have a unique setup a 180" screen and Projector. This AMAZING projector (W7000) has no audio out and no way to utilize audio from Chromecast :crying: How sad... Well I discovered these audio extractors to get audio out but frankly I would love to retain max color, 3d, and 7.1 on DD+ this is not going to be easy. Then I got to thinking how come no one has developed an app which can sync the 2 outputs (multicast) from DDWRT or other at the router / gateway. Or in another way perhaps.
Two questions remain
1) Audio extractor where can I get a cheap but good one ? (seen them exceeding 200 dollars common)
THE BIG QUESTION IS
anyone know how to do this yet or perhaps if I should sell the thing and get a different setup for these projectors I have 3. (kinda committed to the output device already hehe.):cyclops:
This is what I used because the Chromecast wasn't compatible with my TV. (I had video but no audio)
www,ebay,com/itm/291119088532 $29 - has optical audio out.
Impossible to sync audio to two separate sources that are networked...
What you really want to do is get yourself a good AV Amplifier (with HDMI Inputs), not an Audio Breakout.
You will get full Surround support and would plug the CCast into the Amp and send the video from the amp to the Projector.
To answer the second question in your subject, root won't help you here. As @Asphyx said, it's near-impossible to accurately maintain A/V sync between separate networked devices. It requires sub-second synchronization and without some other constant reference not subject to network transmission delay it's very prone to failure.

Don't want to loose the 3d though and according to Wiki (not their ad on ebay) there is no 3d until 1.4 : so how come they are advertising 1.3 with 3d ?
Ohh btw does this device work 1:1 for lag or is there a few ms' wait ?
Thanks guys this really helps

AFAIK Chromecast doesn't support 120 Hz output (so no full-res 3D), though side-by-side 3D should work on pre-HDMI 1.4 as it's not doubling the rate to get L/R.
There shouldn't be any noticeable lag introduced as it's simply a de-embed at the endpoint.

Chromecast with Projector and Audio Extractor...no audio

I have a home cinema projector with no audio out, so in order to make my chromecast work I bought the J Tech DHDMI Audio Extractor. I've seen this exact model discussed elsewhere online, so as far as I know, others have used it successfully with Chromecast.
So my setup is - Chromecast into the IN of the HDMI Audio Extractor. HDMI cable OUT to my projector. And Optical Audio OUT to my sound system.
The problem? No audio.
I tried the exact same setup with my PS3 instead of the chromecast, and it worked - video and audio, with the exact same hookup. So the extractor works and the cords are fine.
I've tried all 3 audio toggles on the Audio Extractor (Pass-through/2.1/5.1) and none work for this.
I've tried multiple reboots and factory resets to no success.
I have heard that the ChromeCast tries to be smart about it's A/V capabilities, and there is a chance it may be looking at the HDMI connection, seeing that the projector has no Audio capabilities, and giving up, but I don't know how to attempt to reconfigure that, and there are certainly other people out there who have made my exact setup work, and I can't imagine what they are doing differently...
This theory does have additional evidence: When setting up my PS3 I had to set the sound set up to "Manual" rather than "Automatic" - in automatic mode, the PS3 said the HDMI connection had no audio capabilities. However in Manual mode it seemed to pass through audio just fine. I wonder if the same is happening with the Chromecast, only it's too "smart" to just push the audio through?
To test that theory I used an HDMI to VGA adapter to try to get VGA into my projector, but had the exact same result.
Finally, I tried to configure the Chromecast with JUST the optical audio out from the extractor without video so that it wouldn't try to guess what the audio was, and then hooking up the video after. Same result. Tried turning the projector/audio extractor on and off a bunch of times too..
Any ideas or suggestions would be greatly appreciated

If you can borrow an HDMI display/TV that has audio, you can try hooking that up first, booting the Chromecast to get audio, then do a hot-swap. That might work, but if it does, it's only a temporary solution and proves your theory that Chromecast is inspecting the audio capabilities on the HDMI side.
HDfury2 works well for me with its built in audio breakout.

Yeah, I think that's got to be my next move if only to make sure the Chromecast is not a lemon.
In case you don't end up getting yours to work. This is what I use to split the audio and use the chromecast on my projector. and it works flawlessly.

The latest:
* Confirmed Chromecast sends audio by hooking it up to a regular TV
* Tried to hook it up to projector through HDMI->VGA connection and still no audio
* Found out that I'm not the only one having Projector-Chromecast-HDMI splitter problems: (I can't post links but go to the AMazon page for the product)
Ugh. Who wants a free Chromecast? I just don't see this working out for me...
So whatever adapter is used must report audio capabilities. Like I mentioned, I have HDfury2 and get audio fine. The one @Znomon mentioned is cheaper though. Then again, it's still close to the cost of a Chromecast, so...

Sorry u can't get it to work if u really want to give the chromecast away I'll take it been wanting to try one out.
Hi. I just registered to this forum to say that I am able to do EXACTLY what you trying to do.
But the trick is the "guy" i'm using. It's a chinese cheap HD Converter that splits hdmi audio into RCA output and hdmi video. I know that I have not that special audio since it is turned on a rca output, but it works.
I bought from a local tech market. And the first one I bought did not work and the difference between them is energy source (the first had not).
Good luck and keep persistent.
PS: If you really want, i can buy one for you here in Brazil and send you by mail... but the postage will cost more than the converter!

So there is no way to hack the audio without other hardware (splitter)? I was hoping maybe bluetooth can be a solution?

Sorry, need hardware to extract it.
Bluetooth, even if you managed to get Chromecast's Bluetooth enabled, paired and sending audio, wouldn't be good because the audio stream would be delayed, unless it also delayed the video stream too but even that would probably not guarantee lip sync.
I'll take it
Deancommie, I'll take it off your hands. I'm a school teacher, so free is the best price.

Time to upgrade to an Av receiver with hdmi input me thinks. Chromecast works flawlessly with my home pj setup.

Should I go with raspberry Pi 2 as Media center

I have already got MK808 android stick, which is 1.2 GHz dual core with Mali 400 GPU.
After using it long as general purpose device, decided to convert it as media centric device, with 2.1 speaker setup
I am facing following limitations,
1. Not able to play HD/1080 videos smoothly
2. Tried USB sound card to connect it to 2.1 speaker, but quality is not good
So I started to look for alternate devices. I liked RPI 2 especially due to it's support, but before buy, I have some questions unanswered
1. Since I have 1.2 GHz device, I am just wondering with RPI 2 being 900 MHz, is it powerful enough device as media PC. Especially can we consider it for future proof (may be 3 years)? I am thinking because, I don't want to fall in situation to buy another device only after next 1 year due to RPI2 limitation.
2. When I add case, WiFi dongle, power cable, HDMI cable etc, it's going to about 75 USD. At this price, there are many choices like,
# Android stick MXIII, which seems more powerful with android support
# Dedicated media player like,
http://www.amazon.in/s/ref=nb_sb_noss_1?url=search-alias=aps&field-keywords=media+player
But I don't know, how to compare those with RPI 2 and conclude which one will be more powerful and future proof
Any suggestion?

I have been using Raspberry Pi 2 B+ for a month as media center with the Rasplex OS. I have tried 1080p, 720p and a few different formats like mp4 mkv, avi etc and they all work fine, even while seeking. The main reason for this could be that the processing/trans-coding of the video is done on the server(the files are not stored on Pi, and no HDD is connected to it.) This all works on a WiFi adapter.
If You can use Plex app on Your Android Stick and use a plex server somewhere, You won't need to buy a Pi. Although You would need to buy Plex pass to come over restriction in Android app I think.
Rpi 1 can run almost limitless video bitrate via smb share. But it has issues with very heavy audio since 1 pi's processing power is not great basically. But mines 1 still run movies with 10mbps video and 5mbps audio well. Above that it starts to buffer maybe its network bottlenecking. Audio quality via hdmi is great. I got a pi 2 just a while ago looking forward to test it with openelec. I have chromecast stick too i think that i wouldn't need rpi if i didn't had media at local share. Chromecast is far more better if u use only netflix, viaplay, youtube, popcorn, etc and can use it with android device phone/tablet.
Thanks for replies.
Has anyone connected it to 2.1 speaker system?
Because, that is my one of the aim.
Can anyone tell quality if connected to AV cable/stereo jack?
And, is it possible to get video through HDMI cable and audio through AV cable to 2.1 speaker?
Can someone, who already have similar configuration, help me out to build similar one.

Yes, it can output both video through HDMI cable and audio through AV cable at the same time.

How do you rate quality through AV cable out?
I believe, AV out doesn't give good quality as HDMI.
Through USB sound card on my MK808, I am loosing bass. Woofer doesn't give any sound.
I am worried, same should not be with RPI as I'll loose all fun of watching movies.
Anybody with 2.1 speaker setup hear?

HDMI is better. My 2.1 system is connected to my LG-tv, so i dont know what quality the 3,5 mm output is.

Unfortunately, my LED TC has onlu audio jack. So, if I connect 2.1 system with it, I get very low volume.
So, only option to get sound from RPI AV jack.
Can you check in your system with AV jack and report the difference in output?
Any though on
RPI2 vs MXIII vs MXQ?

Composite video out quality is pretty good. On OpenELEC, playing 720p live stream Russia Today. Output is classic PAL resolution. Image quality is better than 576p SD DVB-S thru SCART with good quality sat reciever. I have big old widescreen CRT Panasonic Quintrix TV.
If you play any 720p movie, quality will be comparable to DVD player with SCART.
I dont know how is your audio input for these 2.1 speakers. Just single 3 pole 3.5mm or also separate one for subwoofer? If it need 2 connectors then you need 5.1 sound card with (usually orange) center/subwoofer connector.
I think you should turn up your headphone volume on your tv

Ideal for local media or media on a NAS but not being able to access Netflix, Hulu etc (like you can on Android) might be a bit of a put off. Shame really coz the Pi2 is more than powerful enough to support these streaming services

Audiophile question, Winca S160 -> extrenal Dac?

Hello people,
I'm new here (and to Android in general) so if this is the wrong part of the forum, I apologise.
I have a Winca S160 installed in a 2012 VW Tiguan – it’s generally OK, although I’m disappointed it can’t play FLAC audio files.
I’m a bit of an audiophile so about to invest in upgrading the speakers and adding a real amp to the car, however I’m still stuck with the source being a generic android tablet with very little consideration to sound quality…
(I know I could get a dedicated head unit but I need Waze and the parking camera)
So I’m thinking what if I got an external USB DAC (Schiit Modi 2, Fragonfly etc) and then connected the DAC’s outputs to the amplifier etc? That would supercharge the sound quality, no?
That way the S160 acts as a transport (basically a fancy hard drive for the music files), and sends bitstream to the DAC that then renders the music.
The question is that possible? I’m not too familiar with Android in general, but I know there are DACs that work with it.
So hypothetically, if I added a USB dac, will it then act as the soundcard for the S160 and send all sounds through the DAC? Will this mean I could still use the steering controls to change the volume, skip tracks etc? Is it possible to do? Do you see a problem with this?
Any thoughts or ideas are welcome, thank you!

I just installed the winca s310 and the audio is normal which is not very satisfying to be honest and still searching for a way to fix that.

Record what's playing with USB audio recorder or any other app...

Need some help to recorder exactly whats playing with quad dac and the exact same quality, native by software. Don't tell me using another sound card or mics. Can USB recorder do that? Do you know other software? Also it needs to leave quad dac enabled...
Trying to figure out if this is possible and if it has solutions. If not, maybe with a laptop, but what kind of software or external sound card can capture the exact same 32 bit data from the quad dac? Please help.
no UAPP cannot do this. there is no solution short of maybe root and even then I've never come across anything close.
more critically... engaging the quad DAC inherently means you are converting to analog. your request to avoid sound cards or mics is nonsensical, because an analog signal needs to be converted back to digital bro.
FYI if your intention is to rip music from streaming services, that's a whole different operation (encryption etc). I believe it is only possible with Google Play Music (Tidal has proprietary MQA encoding).
just tell me what you're really trying to do, maybe there's a better way.
