I have audio throught HDMI GTX 260 NVIDIA card to two monitors, audio works fine, sometimes at system start I have to mute/unmute to make it work.

My problem is since I move to 11.10 I lost audio randomly in the middle of the session, I can get it back by tipping

killall pulseaudio
sudo rmmod snd-hda-intel
sudo modprobe snd-hda-intel

But its a very aggressive measure, and usually makes my system unstable or even doesn't work and I have to reboot to get audio back. This is very annoying.

Sound worked for me flawlessly in Ubuntu 10.04 (I have to mute/unmute at system start anyway but never losing audio), so I tried Mint 12 and Fedora 16, and the problem is also there, so I think it has to be a kernel 3 issue with my motherboard (ASUS p5k Premium) and my graphic card (ASUS NVIDIA GTX260).

This is the out of aplay -l

EDIT: I'm trying MINT MAYA, sound is working form start, but issues started as soon as I installed the proprietary drivers. If I remove the NVidia drivers (both noveau or the others) I get the sound back working flawlessly. If I decide to use Nvidia privative drivers, I play sound lotto each time, and I usually loose :( meaning my system will have sound some times and will get soundless randomly. There must be something I can change to make sound persistent, please help me.
