No sound over HDMI [solved]

Ah, I had not realized it had already become official! In that case, no problem. Although, I would still be interested to know what you think of my edid dump, since I am having to use the audio force option? I mean, my device clearly does DD and DTS, so why is it only showing 8 ch audio in TV Service without the extra option?

Bump....because I can't PM, and not sure anyone, or specifically Dom is reading this - but if I'm not the only one suffering then I think this could add value to many people.

What's the problem? The hdmi_force_edid_audio option has been supported in official start.elf on github for a coupld of weeks.

Hi

Though it didn't fix my sound. I've tried the troubleshooting page and hello_audio.bin 1 works but aplay is silent unless I send it to the Jack socket. I can get sound in Scratch over HDMI by doing this
viewtopic.php?f=26&t=5903&p=112695&hilit=Sound+scratch#p82680

I really would like to get sound over HDMI working but nothing seems to cure it.

Cheers

Unfortunately, Dom, I can't find where it is documented in the Wiki - not in Troubleshooting, nor in the config.txt - those are the two places I go to look first. It may get mentioned somewhere in the fora, but it's pretty hard to read that whole thing.

And I don't have alsa .wav outout over hdmi right now, although it used to work some days ago... The hello_audio works both ways, and alsa aplay outputs to the analog jack. I'm mystified, because I haven't seen any changes to the alsa driver recently, and we never know what changes in start.elf files - which I update fairly regularly.

I suddenly can't get audio to work over HDMI anymore
It used to work perfect for months and since about 1 week it doesn't work anymore
TV type is a JVC LT-32A70BU.
I've tried everything mentioned above (hdmi_drive=2,...) but nothing helps.
I've used an SD card with Raspbian (with omxplayer -o hdmi) and another with Raspbmc image in both cases no sound over HDMI.
I've tried on another TV and there is works perfect
Replaced HDMI cable but still no sound...
I don't think the TV is in DVI mode because then it's supposed to take sound from the EXT3 analog input and it doesn't do that either.

Anyone has another thing I could try?

Having the same HDMI sound problem after trying all the config options posted.
I have successfully shown that the pi can drive HDMI in a test using /opt/vc/src/hello_pi/hello_audio/hello_audio.bin 1 which works. But no other sound seems to work with HDMI, incuding:
sudo aplay /usr/share/sounds/alsa/Front_Center.wav
Analogue tests work fine.
Target device is a TV rather than monitor.
I have tried to attach the EDID dump in case that helps but all extensions (including no extension) are rejected?

Thanks

You've tried:

Code: Select all

sudo amixer cset numid=3 2

http://elinux.org/R-Pi_Troubleshooting# ... MI_monitor

before running aplay?

Apologies I should have added that too - I did set
sudo amixer cset numid=3 2 prior to trying it

Seems like the TV supports audio still nothing coming out of the speakers

I have further tried hdmi_force_hotplug=1 from another thread in same forum , no change to HDMI sound unfortunately.

Out of all the config options tried I currently just have hdmi_drive=2 as an added line to default config.txt

My EDID is here if anyone can offer advice:

great!
to confirm, I got mine to work by adding:

hdmi_drive=2

to the config.txt (sudo nano /boot/config.txt). thanks all!

I have the same problem and what do you mean config.txt

Do I write that in terminal
