ATI HDMI Audio help needed

Hi,

I've been a long time Linux user and just made the jump to arch. I've recently been using Ubuntu but before that I was running Gentoo, Debian and Fedora.

I am currently experiencing a HDMI audio problem that I just cannot seem to fix (after a good few weeks and 2 different distros used).

My system is on a GA-MA78GM-S2H system board using the on-board HDMI port. This was working fine on my previous installation of Mythbuntu 10.10. On upgrading to 12.04 my audio stopped working. After a lot of tinkering I decided to do what I've been thinking about for a while and put off which was to move to Arch. However, I am experiencing the same issue on Arch. So I am asking for any help in getting this problem squashed.

Useful information for you on the system

01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series]

Things tried so far.

  1. Set 'radeon.audio=1' in both /etc/defaut/grub GRUB_CMDLINE_LINUX_DEFAULT= and also in /etc/modprobe.d/alsatest.cont

  2. checking audio is unmuted in alsamixer for both the standard card and c1 (c1 only lists a spdif but this is unmuted

  3. confrimed that audio is playing out the analog ports fine

  4. Various other things I've forgotten

aplay -D plughw:1,3 xxx.wav acts as if it is playing (no errors) but doesn't play sound. but if I try to play through audacious as a test then I get an error about being unable to set the number of channels. I was getting a similar error when trying to use aplay on the recent ubuntu install as well.

Any help or advice would be very much appreciated :-D

Re: ATI HDMI Audio help needed

I forgot to mention in the post that I've been using the open source drivers (xf86-video-ati). I've yet to try the catalyst ones, but according to the xorg Website HDMI audio should be supported for the RS780 chipset. I can move to the catalyst drivers if that's what it'll take, but I'd rather have confirmation that it works before I do it.

Re: ATI HDMI Audio help needed

Last time I tried HDMI audio (about a year ago) there was no support for it in the open source ATI drivers.

Have you read https://wiki.archlinux.org/index.php/ATI#HDMI_Audio yet?

Best of luck!

Re: ATI HDMI Audio help needed

Thanks for the response.

I actually decided I may as well upgrade my sound system, so I am waiting for a new amp and speakers to run out of the analogue connection.

I've been through that page, everything seems to work, it's just when I do aplay -D plughw:1,3 etc. I get no output. I may try the propitiatory drivers when I get some time after Christmas. If I manage to get it working I will report back for other peoples information.
