Can't adjust soundcard volume with 2.6.25

Hello ,

I upgraded to 2.6.25 a few minutes ago and rebooted as usual.
Everything seems to work fine, but I can't adjust my soundcard volume with gnome-volume-control anymore. It will reset the left channel of every control(Master, PCM, even Line-In. Just everything) to 6% if I try to move it. The right channel works as usual.
I can adjust my soundcard volume with alsamixer on the console perfectly.
I also tried to create a new user. The problem persists(but a bit waker). I also tried KDE/KMixer, everything is fine there.
What can I do?

Thank you,
eiffel56

Re: Can't adjust soundcard volume with 2.6.25

Hi,

I guess I have the same problem since 2.6.25 with gnome-volume-control. I can't adjust the volume, when I try to set the Master volume it jumps randomly, sometimes it adjusts the volume only for the left channel. I've read that this is a known problem (here: http://bbs.archlinux.org/viewtopic.php?id=47784), but I don't know what causes this problem.

The first time I noticed that bug was after the kernel upgrade to 2.6.25 after I tried to switch the volume level with the mouse wheel. It jumped around, it was not possible to set the volume I wanted to.

I'm running PulseAudio, now I use 'pavucontrol' to set the volume level.

Re: Can't adjust soundcard volume with 2.6.25

Hi,

thank you for your answer chris89.
Yes, the left channel control thingy jumps randomly. If I try hard enough, the left channel will remain at 100%. It will jump back to 6% if I try to set it to another value.
I use ALSA.
Seems that its a bug in gnome-volume-control. I wonder why it didn't happen before... . And why the hell it is not fixed, according to your link the problem itself is older.

My current workaround is to use KMix. But thats..well...ugly .

Re: Can't adjust soundcard volume with 2.6.25

Sorry I don't have the answer to the problem, but just wanted to let you guys know that the volume control in Gnome seems to be working fine for me with the new kernel so maybe it's hardware specific in some some way.

Edit:  what I mean is hardware/kernel specific.

Re: Can't adjust soundcard volume with 2.6.25

hi guys!

Intel Corporation 82801 (ICH6 Family) AC'97 Audio Controller (rev 04) here
using module snd_intel8x0.

i'm glad, i'm not the only one affected by that problem

i've seen gentoo-people reporting the same weird behaviour.
so i think it's not archlinux-specific.

Re: Can't adjust soundcard volume with 2.6.25

Yaha, also snd-intel8x0 here. Realtek ALC850 rev0 onboard chip.
So, maybe a bug in 2.6.25? Maybe alsamixer, KMix, ... uses another method to set the volume than gnome-volume-control, and the gnome-volume-control method is broken or something.
By the way, a workaround for me is to use the OSS mixer, works great. But I don't like that solution...

Didn't have this problem in any distribution that I tried before or with any old gnome version since i use gnome.

That's strange, because my soundchip is also an Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 04) ...

Kernel-Version: 2.6.25-ARCH (i686)
gnome-volume-control:
[*] --version shows: GNOME gnome-volume-control 2.22.0
[*] the GUI info dialoge shows: 2.22.1
ALSA: 1.0.16
Gstreamer: 0.10

(I don't know what else I should post here to compare it with your configuration - maybe we find something useful for a bugtracker)

Re: Can't adjust soundcard volume with 2.6.25

maybe there is a twisted module?
http://ubuntuusers.de/paste/226555/
that's the output of "lsmod | grep snd" - tomorrow i'll try to disable some modules...
maybe they screw around with alsa (or something else).
but right now, i'll to bed. it's 11pm here in germany

Re: Can't adjust soundcard volume with 2.6.25

Mh, I think I've found something interesting.
Close all apps that access the mixer. Close alsamixer, close KMix, delete that speaker-icon thingy in your panel. Set everything in gnome-sound-properties to anything different than your soundcard(e.g. the first ones to ALSA, "Default Mixer Tracks" to another soundcard or your soundcard with OSS mixer).
Now open gnome-volume-control. Start music or something and access your soundcard with gnome-volume-control. You will notice that your controls will work MUCH better. If you re-enable all your stuff(open alsamixer for example) you will notice that it is as bad as before.

Can you confirm that?

Yep I can confirm that. Strange... I killed pulseaudio, removed the volume control icon from the panel, started gnome-volume-control from a terminal and then it works properly.
