HDMI out sound problem

Hi
I am trying to use my LG P990 as a car pc.
Now the screen in my car is 7" and only has a vga input.
Audio is played on my car's stereo system using rca or line in cables.
I bought a converter for this case HDMI-VGA from König:
Connectors: 1x input HDMI female
1x output VGA + 2xRCA female
• Supports HDMI resolution: 480i, 480p, 576i, 576p, 720p, 1080i en 1080p
• Supports Analogue Video output up to UXGA and 1080p with 10-bit DAC
• High performance up to 1.65 GBps/165 MHz
• HDCP 1.2 support
• LED indication power.
• Built-in equalizer.
• Power: 5V
Once I use this converter the HDMI mirroring from the LG P990 works on my 7" car screen no problem.
But the audio is only played on my phone and is not passet through by the rca cables to my car audio system.
I checked if there are any options of changing the audio output but couldn't find any.
Normaly when I use the mirco HDMI to a tv it play's video and audio through the HDMI cable on the screen.
But now it only play's on the phone it's speaker.
I can still get the audio to work on my car's speakers by using the headphone 3.5 line out.
But this means an extra cable coming from my phone wich I rather loose.
I tried other devices with this converter but only my PS3 will send sound through the RCA to the TV, however no video.
I contacted König with my problem and will post what they tell me.
But I think the problem is with my LG P990 audio out.
Any idea's?

I think the problem is simply your phone not recognizing your setup. Your best bet might be using the minijack connection, might be an extra cable but saves you the hassle.
Also this is the wrong section, should be in Q & A.

sorry for wrong section, I don't think I can change that now.
Is there any way of force audio output?
Or selection different options?

Well it's clear what is causing your problem, but I don't think you'll be able to fix it. As you proved with experimenting, HDMI devices are having problems with recognizing what they are connected to. Maybe you've got a bad unit, maybe it's a general problem with design. Use warranty to get new one, if that doesn't work try to get your money back and buy something else. Can't recommend anything, sorry.
But, interesting project! Not so long ago I was thinking about going that CarPC way too and now it's easier than ever . You will not have touch input on 7" LCD but anyway...

[Q] Using HDMI to DVI converter with AUDIO

Hello all,
I am having an HDMI IN to DVI converter on my monitor, and I am unable to buy HDMI to DVI with Audio converter right now.
Is there any way where I can get the audio from 3.5mm jack/phone speaker instead of HDMI itself? The reason is audio signal is lost when we convert HDMI to DVI.

If you have a speaker system with an External source, plug it in there. Alternatively, you could plug it into the Mic port and tell Windows (Which I assume you're using!) not to mute any of the input.

I have a speaker system, can I plug it in the 3.5mm jack output of my phone and at the same time use HDMI as a video source? I thought when using HDMI port, the 3.5mm jack audio of the phone would be disabled.

it should work cause the HDMI audio is intented as the speaker of the phone then plugging in the 3.5" jack it should switch to it...

Chromecast audio troubles

I´ve been reading this through these chromecast threads and I cannot seem to sort out my problem..... I have Samsung UE40EH5000 tv and Sony STR-DG700 receiver. I have tried plugging chromecast into both tv and receiver but I am only getting sound out of the tv speakers. I have run HDMI from receiver to tv but no sound from receiver, I have also tried audio cables into the receiver from the tv but no sound. I have an ipod and satellite running through receiver working fine. Please help me x

Most likely it's just your TV settings - it probably doesn't support ARC (Audio Return Channel) as I don't see it mentioned in the Quick Setup or Manual.
If that's the case, you need to run the Digital output from the TV back into your receiver. See page 66 of your TV's Quick Setup (which IMO is a better "manual" than what Samsung calls the manual).
Set your TV's Speaker Select to External Speaker. It says that on TV Speaker it should have sound out both the TV's speakers and external output, but at least on my Sony TV and Sony sound bar, having both on produces a strange echo effect.
(See page 53 of your TV manual)
Also check on your receiver that the HDMI port has been properly assigned to the input that you're using.
(See page 66 of your receiver manual)

I actually think this is a problem on his Amp side....he did say that he tried plugging into the Amp directly and got the same result.
If his TV doesn't support ARC he could use an Optical cable from the TV to the Amp and that would work.
But he might need to check the Audio settings on his AMP for that particular HDMI port.
Not sure about the devices he says works but I wouldn't expect a IPod to plug into the same HDMI plug he was trying to use and most older Sat boxes usually use an Optical input instead of the HDMI.
And you can change the Input on most Receivers to set what Audio source to take from be it optical or HDMI.
He should check the settings for that particular output and see if the Audio is set to HDMI.

Many thanks guys for your help but its still not working, I haven´t tried an optical cable because I need to buy one and they are about 30-40 euros here, and I thought audio should run through HDMI.
The chromecast is from the USA and I am in portugal will that make a difference?
Here is my setup....Chromecast plugged into TV, HDMI cable plugged into TV and run to receiver (3 HDMI ports on receiver, not sure which one is correct, but have tried all three I think!!)
Have tried with TV speakers and external speaker settings on TV.
I have tried the HDMI menu on the receiver.
Will an optical cable be the solution?

Ouch, that's horribly expensive. Optical cables should be US$10 or less, though you can definitely spend more. But optical cables do not need shielding the same way electrical cables do.
Not sure where you are, but here's a quick search on Amazon UK for price comparison

If you hear audio on your TV, then yes, the optical cable will solve the problem by sending the decoded audio from the TV back to the receiver.

Yes Optical would solve your problem, The wiring you described would only work if your amp and TV support HDMI-ARC which really requires a more recent TV and AMP. That port is usually specially marked on both the TV and AMP side.
I'm betting most of the cost of that cable is in the shipping.but Ebay has a slew available that would bring the price down.

Many thanks guys the optical cable worked straight away, I managed to buy one local for 15 euros, was worth it!
One other issue I have come across which you may or may not be able to help me with.
One of the things I want to do with chromecast is run karaoke videos from YouTube, I have a mixer the microphones are plugged into but I found the optical sound was overriding the sound. I have sound from the tv (youtube) but no sound from the microphones, If I unplugged the optical cable I lose sound from the tv and get sound from the mics.
Is there a way around this?

What's the make and model of your mixer?

Not sure and I´m not with it! Will post tomorrow.

Not sure thats possible because the Chromecast takes the content directly from their servers if I'm not mistaken.
You would have to take the Output of the Audio from the TV or Amp and Mix it all Post Chromecast.
Easiest way....
CCast into TV, TV into Mixer, Mic into Mixer, Mixer into Amp. Amp to Speakers
If your mixer has an Optical Input that can be mixed all the better but most likely your going to be Analog from the TV to the Mixer.
You CAN get a box that will pull Audio out of an HDMI signal to analog as well but it's overkill since the TV will give you the same thing already.

Sounds like it might be a mix of analog and digital in the path. Will wait for tomorrow's update.

New TV, no RCA out :(

Hi guys,
I bought a new Samsung TV the other day; it has RCA input but no RCA output.
I have some wireless Sennheiser RS170 headphones that connect via headphone jack or RCA output. The headphone jack works fine but mutes the tv speakers, so every time l'm not using them have to remember to unplug them (on the back of a 46" tv!)
However, connecting via RCA, I can leave them plugged in and works ok.
Anyone know how I can get RCA output on the tv, if at all? I seen some scart to RCA output adapters, would this work?
Cheers.
Owen.

if you had a receiver amp you could plug the rca in to that, or I believe if the TV has an optical output (should have) you can get a converter to change the optical out to an rca. http://www.amazon.co.uk/gp/aw/d/B0074JZ8ZW
sorry to say but most new TVs only have an optical out these days to run audio to a sound bar or amp.
you can get a two rca to a 3.5mm jack plug which would fit in the headphone socket of the TV but you would likely have the same prob of muted TV speakers.

[Q] Why doesn’t chromecast output audio through TV's external speakers ?

Here is my set-up:
A Vivo LTV42FHDN 42” Full HD TV (2x HDMI inputs, 1x RCA stereo audio output, few other audio and video input connectors, and a set of really crappy built-in speakers)
A Logitech 2.1 Speaker system connected to TV's RCA audio output
An old DELL XPS M1330 notebook running Windows 7 hooked up to the TV via one HDMI port
A new Chromecast I’m trying to setup connected to the other HDMI port.
When I watch TV and switch to the HDMI input of the PC I get audio through both the TV’s crappy built in speakers as well as the much better sounding Logitech Speakers. However, when I switch to the Chromecast I only hear audio through TV’s built-in speakers. I have connected other PCs and tablets through HDMI before and from what I recall, sound always came out external speakers.
Is there any reason for the PC and Chromecast to behave differently when connected via HDMI ? I tried both HDMI ports, went through TV's audio settings (which only has very few settings like bass, treble, and some sound profiles), but couldn't get the chromecast to output audio through external speakers.
Does this mean Chromecast doesn’t support somesort of an HDMI specification/standard my old PC does, therefore the TV can't split and reroute the audio ? Is there any way to get around this without buying new hardware ? Other than audio, rest of it works great ! For me spending $50 or so extra on additional hardware really defeats the purpose of buying a Chromecast, because for that price I could've bought a DLNA enabled media player.
Any help appreciated. Thanks.

I'm not sure about your LG, but my Sony correctly re-routes audio from Chromecast to SPDIF (optical) output connected to AVR, so the Chromecast isn't a problem. I'm not sure about analog RCA output though.
Just go through your TV settings again. There must be an option burried somewhere in menus.

Thanks for your reply, I did go through all the settings on the TV and even read the manual. But couldn't find anything there. Its not a very high-end TV, hence no optical output, all I have is that stereo analogue output.
Few minutes after posting I again connected my new notebook, and a Windows 8 tablet, audio works fine with all of them. But the Chromecast just doesn't work the same way. When I tested I connected all devices to the same HDMI port and didn't change anything on the TV, all I did was plug one in > test > unplug > plug the next one in > test etc.. that's all.. the fact that everything but the Chromecast work has to mean there is something different in Chromecast's HDMI signal.

Try switching the audio output in whatever application you're casting from to Stereo.
If Chromecast is sending multichannel audio, your TV might be smart enough to decode and play it on its speakers, but not smart enough to downmix to the analog output.

Hi,Were you able to resolve this problem? Chromecast works great except for this exact same annoying problem. Also have the same TV. Thanks.
