Sound over HDMI problems

Hi forum,
I have strange problem. I want to use a Xen HVM Domain with a ATI Card as a HTPC (got this working with a ubuntu 11.10 - want to migrate to arch). Basically everything is working with the catalyst drivers besides some sound problems. Following what is working:

with smplayer (alsa output):
- mp3, avi, mkv
vlc (with default sound - probably pulseaudio):
- mp3, avi
mkv is like stuttering and the movie gets interruped very often.

vlc (with alsa output):
- mp3, avi, mkv

mkv is like stuttering and the movie gets interruped very often.

Flash videos are showing the same behaviour - stuttering a lot.

**** Liste der Hardware-Geräte (PLAYBACK) ****
Karte 0: Generic [HD-Audio Generic], Gerät 3: HDMI 0 [HDMI 0]
  Sub-Geräte: 1/1

What i tried:
.asoundrc:

pcm.!default {
    type plug slave.pcm {
        type hw card 0 device 3
    }
}

This worked on ubuntu 11.10 but not on arch!
btw: ubuntu 12.04 does not work neither.

in default.pa i load the alsa sink module with hw:0,3 too.

behavior did not change.

any ideas, what is causing the problem? I really dont wont to switch to gentoo just to have a system without pulse (what is maybe the problem?).

Re: Sound over HDMI problems

Hi,
I have some news. With Kernel 3.3 and 3.2 it is not working! Using the LTS Kernel everything is fine! Any Ideas about this?
