Comment 37 for bug 1321421

I have Gygabyte GA-Z97-D3H. I assumed motherboard will work in Linux out of the box, without problems - what a stupid assumption.

Sound was cracking and distorsion.

After adding /etc/modprobe.d/alsa-base.conf
     options snd-hda-intel vid=8086 pid=8ca0 snoop=0
speakers are working but there are two problems:
- after inserting front mic/headphones, the sound stop going out to speakers (back connector), although in Ubuntu settings I set it to go to both
- microphone is still distorted. Every 3-4 seconds or so there is a "tick" and it annoyed my skype connection

Thefore this "fix" still has some problems :-(.

Pitty I bought this motherboard, if I was aware of the problem I'd bought another older motherboard without PCI M.2

If someone knows how to solve the problem with microphone shoot, in the meantime I'll plug USB microphone/headphone to see if it could fix the problem.
