after upgrade to kernel 3.6 something is wrong with the sound. Namely there is significant noise in multiple applications.
Affected applications: vlc, skype, xnoise.
Not-affected applications: xbmc, flash, wine.
Switching back to kernel 3.5 resolves the problem.
I have 2 sound "cards" in my laptop.
According to alsamixer they are: HDA Intel PCH (primary) and HDA Nvidia (probably on GPU with HDMI output).
According to lspci:
- Code: Select all
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
01:00.1 Audio device: NVIDIA Corporation GF116 High Definition Audio Controller (rev a1)
I'm using only Intel's one.
So, I assume the noise is a kind of kernel/alsa+kernel issue.
Is there any solution for it?
Or maybe I should report a bug?
Thanks in advance
