[Silverium <soldeplat@xxxxxxxxx>]

Public bug reported:

It works properly for some time.
Then, in a sudden, sound output is multiplied and distorted.
Then, there is no way how to configure it to make it work properly. I need to reinstall drivers and reset computer.

I did:
sudo m-a update
sudo m-a prepare

rm -r ~/.pulse ~/.asound*
sudo rm /etc/asound.conf

and later reset and everything works for another while.

But problem comes again and again.

My system runs Ubuntu 14.10, 64 bits
