Bug Description

if i unload the kernel module snd_hda_intel
and then load it again, sound works perfectly (on external spakers)

but sometimes this doesn't work (snd_hda_intel is in use...)
i added this to my rc.local
rmmod snd_hda_intel
modprobe snd_hda_intel

sometimes it works (every 5-6th boot)

this appears in egdy,dapper and feisty

Thank you for your answer.
I found a temporary solution for this.
I have to kill pommed before I remove the moule from the kernel...
It's a very dirty solution, but works until something better arrives.

I attached the requested files.
