 Posted: Tue Jan 29, 2008 9:34 am Post subject: Sound mixer troubles after new kernel |
 |
|
I recently upgraded to the 2.6.23-gentoo-r3 gentoo sources from the ck sources (2.6.21-ck) and I noticed a somewhat wierd behavior with my sound mixer. Muting or raising/lowering the level on the Master channel no longer disables all sound. The only channel that seems to have any impact is the PCM channel. It makes sense that the PCM channel has impact, but why won't the master channel work or do anything?
uname -a

I don't nave a solution to your problem but i can confirm this problem also exists on my desktop with it's NVIDIA HD sound card.
PCM channel works as expected, but master channel has no effect while the center channel seems to have the same effect that one would expect master to have. |

| You could try to pass the model= parameter for the sound module. Here is a description of valid model-parameters. |

How can I figure out what specific model name applies to my soundcard?
lspci says it's an Intel Corp. 82801G (ICH7 Family) which isn't listed in the models under snd_hda_intel in the document you linked above.
The default seems to be working except for that master channel. It worked perfectly in Kernel 2.6.21-ck -- I booted that and I don't see anything different in proc or "lspci -nv".

Tried every single module= option to no avail. Main really serves no purpose.
I was able to pinpoint that the 2.6.22x kernel is where it started. Both my 2.6.22-ck1 kernel and my gentoo sources kernel exhibit this behavior. So this is potentially a driver-level issue and not a config issue.

| I believe it is a driver issue. The intel-hda driver still has issues and is updated every alsa version. Have you tried the newest alsa-driver-9999 package? |
