The sound on my machine (Medion Akoya S5610) works intermittently. If I reboot enough times I do get sound. This happened before I upgraded, when running Oneiric too. I have fiddled around with alsa-base.conf, putting in different values for model in options snd-hda-intel model=but still the issue persists (although I get the impression that I am more like to have sound on the next reboot if I have edited that file although I can't be sure of this). Adding index=0 does not help the situation either.

I have been thinking that this problem could be related some how to the order that driver modules are loaded. The snd-hda-intel module is also used for the sound card (ALC888) in my graphics card. Could it be that these are some how competing? If so, how do I add a preference when they are using the same module?

This is the result of lspci -nn | grep Audio (when sound was not working):

00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)
01:00.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI RV620 HDMI Audio [Radeon HD 3400 Series] [1002:aa28]

I've been wrestling with this problem for ages and ages and have spent days looking for answers on forums but to no avail so I would appreciate any help you can give.

Many thanks
