I've an Asus Z92V, I am running Ubuntu 12.10 and since I installed Ubuntu on this notebook the audio keep crackling and popping continuously. Moreover the volume bar on gnome-shell panel keep jumping from low volume to high volume continuously. This is indifferently through speakers and headphones...it's an unbearable and annoying problem!!! Since it's a common problem of Intel-HDA-audio I've found a lot of solutions and hints around web, but nothing has solved my problem...
This is the output from
lspci -v | grep -A7 -i "audio":
00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04) Subsystem: ASUSTeK Computer Inc.

I tried to mute / unmute all mixer channels (via alsamixer), but it didn't change anything.
Please help me, guys... Thanks
