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.

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.

When I edit the config.txt file (with the OS) using the command: "sudo nano /boot/config.txt" It seems that nothing has been recognised. But when I check, it has been changed.
I in putted:
hdmi_group=1
hdmi_mode=16 (for 1080p60 resolution)

Have I missed a step to get the boot sequence to recognise these instructions.

Ok, I have updated the config.txt file but with not luck. I ran tvservice -m CEA and worked out that my TV can run at 1080p60. This means that it should work. Can someone please explain what is going on.
Note: Config.txt:
hdmi_group = 1
hdmi_mode = 16
hdmi_drive = 2

Is something wrong here?
Also, I edit the config.txt file using "nano /boot/config.txt" then close it by using "ctrl + o" then "enter" then "ctrl + x"
Is something wrong here?
Should I be placing the file in the /boot/ directory from a different device?
Please help as I woud like to have sound and full HD output ASAP.
Thank you.

Going to try and start from scratch, new image, new config.txt file, etc. If this doesn't work then I don't know what to do?

Hello Fergus,

Might be a good idea to start again. I'm no expert, but your config.txt looks OK to me. If you are gonig to re-install, get the latest debian squeeze image from the Foundation's download page as that solved a few problems for me.

If all else fails, I would try and post a message over in the foundation's forums, there is someone over there called Dom who appears to be Broadcom's HDMI guru. Post your edid file there and hopefully he will show up and help.

Dom doesn't seem to be responding or the community forums don't want to put up my messages. Will try and fix RPi when I get time.

Hi Fergus,

I was fiddling around with trying to play an MP3 at the weekend, and couldn't get it to work, until I tried the instructions on this page http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=4958&p=61894&hilit=alsa+mp3#p61894 second post down.

After a re-boot, the included Debian sound player actually played my mp3 files. Didn't have much chance to test it further, as I had firmware flashing problems on another device !

Hope this helps a bit ?
