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. Asus A6VC
Flags: bus master, fast devsel, latency 0, IRQ 41
Memory at febfc000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>

Kernel modules: snd-hda-intel

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

Please help me, guys... Thanks

P.S. output from sudo lshw -c multimedia:

    Maybe this helps http://askubuntu.com/questions/138266/distorted-choppy-audio-in-precise – Misery Apr 06 '13 at 18:25
  • Thank you Misery, I've added that line in my alsa-base.conf and now sound from speakers is working fine!!! But sadly, now headphones audio is mute, why??? – Balez Apr 18 '13 at 17:01
  • Did you connect headphones to the same plug as speakers? I mean: disconnected speakers and connected headphones in the same place? – Misery Apr 20 '13 at 05:23
  • No, I use internal speakers (it's a notebook)...anyway yes, I connected headphones in the right input... – Balez Apr 20 '13 at 20:31
  • Maybe the problem is in the model=generic...I think that model doesn't allow me to use headphones. I've tried a lot of other models, like described here: (https://help.ubuntu.com/community/HdaIntelSoundHowto), but none of them worked :-( :-( However thanks a lot Misery, at least now audio from speakers works fine!! – Balez Apr 20 '13 at 20:42

A possible solution is disabling "auto-mute" in alsamixer. It is used when the "switch-to-headphone-and-back-again" bug occurs (in high volumes mainly).

First, open your terminal, or press:

CTRL + ALT + T

Then, type and hit "enter":

$ alsamixer

This screen will show up:

Alsa mixer screen in terminal

Use the right arrow until you select "Auto-Mute"

Then, press the down arrow to set it do "Disable" (see the text above it).

That's it.
