Hi guys!
I have this problem long time. The overheating may not explain the
issue, however the issue itself is closely connected to the power
management of the hardware.
I investigated the problem and it is basically caused by the decision of
the HW to switch the mode of the circuit (programma
I believe there is no solution and most likely will not be.
Why:
- The problem occurs in most cases after the warranty period.
- It is also somehow linked to the hardware deeper then one would expect
(seems it lies somewhere in the Intel HDA switch/firmware programming).
Although I still believ
Right, this works to me too, however it brings the sound back for
unpredictable timewindow. With the overall increased laptop load it
stops working very quickly. I made a bash script that sets the power
state to zero every 0.1sec which works, however the result in weird
crackling sound every 0.1sec
Sounds weird. As far as I know the radeon is graphics card driver. The
problem with the sound is snd-hda-intel driver related
Would it be possible that it is more related to the power management
that regulate the increased heat produced by the Radeon card (when is)
controlled by the proprietar
Found a crapy workaround here: http://lkml.org/lkml/2013/1/13/11
Get the hda-verb (e.g from here:
https://launchpad.net/~diwic/+archive/ppa/+build/2768994/+files/snd-hda-
tools_0.20110516%7Eoneiric1_amd64.deb )
Extract the 'hda-verb' from the deb package and then run as root:
hda-verb /dev/snd/h
Try this: https://bugs.launchpad.net/ubuntu/+source/alsa-

As seems this bug is the same or very similar.

Observations when investigated with the HDA Analyzer (http://www.alsa-
project.org/main/index.php/HDA_Analyzer)
What happened:
1. reloaded the snd-hda-intel driver
2. started the HDA Analyzer in monitor mode.
3. started the VLC and started playing clip => speakers still produce sound

Public bug reported:
The sound works ok and after a while fails/disapears. Can not identify
what I did, however it was ok month or two ago.
I occassionally update recommended updates. My system uses new
backported kernel that is not original to Ubuntu 12.04, however with the
original updated kern
