The link to "HOWTO: Compiling and running radeonhd with HDMI audio" is broken. It is liked to supporthttp://blah.blah.blah instead of http://blah.blah.blah.

Yeah I realize now that the radeonhd doesn't support DRI for the HD3200. I have also tried installing the Catalyst 8.9 driver, the version which the CHANGELOG mentions HDMI audio support. I've tried muting and unmuting, just can't get audio to work.

So now my plan is to go back to Catalyst 8.11, using DVI-to-HDMI and try to get optical out to work. If I can do that, then my last problem is video tearing during playback.

I was wondering if you had any more ideas or suggestions for this? I need both the HDMI Sound + Direct Rendering OpenGL for my setup (a Boxee machine).

Unfortunately at the moment radeonhd does not support accelerated video/2d/3d, although this is something that I hope will arrive for Christmas. At the moment if you need OpenGL your only option is the ATI Catalyst drivers. As to why it's not working with ATI's driver I am not quite sure, but the HDMI audio support in fglrx is buggy as you can see, since the radeonhd driver works with it no problem.

I'm running Ubuntu 8.04, with the ATI Catalyst 8.11 driver. I have a motherboard with the ATI Radeon 3200 video card. I cannot get HDMI out to work with ATI's driver. I follow your guide for compiling the radeonhd driver. When I did this, sound via HDMI worked beautifully for me. However, Direct Rendering was off, which was causing big OpenGL problems for me. I switched back to the ATI drivers, and I cannot get the sound to work over HDMI.

Thanks for the feeback. I'm glad it isn't normal. When I'm watching certain movies the sound is absolutely perfect although the video tears a LOT. But last night when watching Casino Royal the audio kept dropping out but the picture had little tearing and was very smooth. I'm using VLC and playing to a Plasma screen. I'm wondering whether VLC or the screen handles DTS badly and perhaps it is the audio type that is wrong?

Either way I'm taking your direction and moving to the radeonhd drivers. I'm praying the tearing stops and the sound becomes perfect.

Thanks again.

Great article. I have the same motherboard and can get sound over HDMI. The problem is that for some DVDs on vlc the sounds cuts out for short periods (30 seconds) before starting up again. I have ubuntu 8.10 with the 8.10 catalyst drivers.

Is this normal? Plus I cannot get SPDIF to work, whilst using audio over HDMDI.

No this shouldn't be normal, does the video stutter at all at the same time? Can you try upgrading to Catalyst 8.11? In regards to SPDIF, as far as I am aware (correct me if I am wrong here though) you can only choose one output audio device, since we are changing the audio output default device to be HDMI then that is where the audio will come from. I guess you could do two things in the situation. Set the SPDIF to be the default audio out device and then when you require HDMI audio specify the HDMI audio device within the application you are using. For instance using mplayer you would use -ao alsa:device=hw=1.3 (for me anyway, the 1.3 may be different on yours, which it shouldn't be since it's the same motherboard).
