How to get sound over HDMI working when using a TV?

I have tried everything I could find on the internet but nothing has worked. I have a HD TV and the Raspberry Pi is connect through a HDMI cable. I have tried to change the config.txt file with hdmi_drive=2 (didn't work) and tried nothing in config.txt, I have tried sudo modprobe snd-bcm2835 as well but nothing I do seems to be working. I installed vlc but it gives me an error: "VLC failed to initlalize your sound output device (if any). Please update your alsa-lib to version 1.0.23-2-g8d80d5f or higher to try to fix this issue". The help on the Raspberry Pi Forums is not very helpful...Example: "yep, got it playing videos, video games, and just plain music". Can you please help me so that I can move on to some basic operations. PS: I have NO Linux knowledge so please be very specific with instructions.

Fergus, have you tried the rest of the Help wiki ? http://elinux.org/R-Pi_Troubleshooting#Sound

cd /opt/vc/src/hello_pi/hello_audio
make
./hello_audio.bin

Not sure what you are trying to play, but Quake sound doesn't work and I couldn't get it to play MP3 files, I think because it probably doesn't have mp3 drivers as default, although just looking at the forum, the modprode command is supposed to cure that.

What are you trying to play and can you hear anything through headphones ?

Oh, and you are probably already aware, but the search function on the Pi forums is about as much use as a fish on a bicycle, use a Google site specific search and you may get something a bit more useful in response.

Steve,
Does your unit have a CE/FCC mark?

In message #12 of this thread:
http://www.raspberrypi.org/forum/troubleshooting/kernel-panic-not-syncing-attempted-to-kill-init

there is a photo (the last one) of what appears to be a sticker with a CE mark,
but no FCC mark, on the back side of a unit from RS.

I am trying to get any sound possible through the HD TV but can't. not even ...
cd /opt/vc/src/hello_pi/hello_audio
make
./hello_audio.bin 1
... is working through the TV. But I can get audio through the audio jack when I type "./hello_audio.bin 0" .
I have read through the wiki but nothing seemed to help fix the problem.
I am not sure if the modprobe command worked but I think it did (I typed it in and no errors occured).

Also, If it helps, I am running the latest Debian Squeeze image.

The TV is registering the Raspberry Pi as a DVI device. How can I change it to resister the Raspberry Pi as a full HD device?

Fergus,

Have you the suggestions in this thread ?

http://www.raspberrypi.org/phpBB3/viewtopic.php?f=6&t=5062&p=67263&hilit=dvi+hdmi+force#p67263

I think you are correct in that the TV is registering the Pi as DVI rather than HDMI.

If none of that works, perhaps you could dump the EDID file in the same thread and see if Dom can help you as he seems to be the expert on this topic over on the Pi forums.

@Coder: Been away this weekend so will check when I am back and let you know re FCC/ CE mark.

@Coder: Mine is the same as the picture you link to, this is a photo of mine. It is a stickered CE Mark.

Get's recent post on Setting up HDMI output - http://www.raspberrypi.org/phpBB3/viewtopic.php?f=5&t=5851 - probably supplies the detail(s) you need to overcome the issue.
