Description sean finney 2010-05-08 04:16:47 UTC
I've been using the radeonhd driver for some time due to the fact that it supports audio over HDMI, so i can have everything routed to my HDMI receiver over one cable.

I read that recently the radeon driver was supposed to offer support for this as well, and since it's otherwise a better driver i thought i'd give it a go.  unfortunately, i am greeted with the sound of silence, and not hte simon and garfunkel version (which would equally be surprising, but...).  if i switch my xorg config to use the radonhd driver audio still works on this machine, but without running x or with x running and radeon driver loaded, nothing.

alsa sees the devices, and I can play to it via sox, but I don't hear anything.

here's some info that might be useful, please let me know if you need anything else.

Patch against 2.6.34-rc6 to fix the problem
Comment 2 Christian König 2010-05-09 11:56:10 UTC
The initialisation path for the IGP version of the chipset is missing a call to r600_audio_init, so audio isn't enabled on those chipsets.

I've attached a patch to fix the problem, but beside from a compile check its completely untestet since i don't have access to an IGP version of the chipset.

sadly, no love, still silence.  thsi is the last i see in dmesg:

Comment 5 sean finney 2010-05-10 13:26:13 UTC
okay, this is really interesting... when the system starts up after booting/rebooting, the audio does not work.  attempting to play to the alsa audio device will result in various errors having to do with sysctl requests *but*, if i restart the graphical user session (i.e. /etc/init.d/gdm restart), the audio works!

it only seems to be in 2-channel stereo though, but i'm not sure if that's just me needing to find the right modprobe option foo to snd-hda-intel.
