[P55-UD4P, ATI R6xx HDMI, Digital Out, HDMI] No sound at all

[Ryan Lovett]

I used to have audio in natty and after upgrading to oneiric there's nothing. When I play an mp3 in mplayer or totem, the elapsed playback time increases faster than regular time. All of my mixer settings are up, same set of speakers, etc. Oneiric was the only change.

I switched to the fglrx display driver and rebooted and I've gotten my audio back. I also used fglrx in natty.

This is a known issue. The radeon driver in linux 3.0 forcibly disables the
audio output by default.

In case I want to move to radeon, do you know how one enables the audio?
Or is audio disabled for good reason?

Thanks,
