Asynchronous sound regulation?

Hi there.

After a few hours of searching I've managed how to make my volume wheel work with archlinux. Im decreasing and increasing volume level with commands:

 amixer -q set Master 5%+ unmute

and with "-" to decrease respectively. At the sound level 5-15% strange thing happens: my left channel volume level is faster decreasing than the right one. I've tried also this method: https://bbs.archlinux.org/viewtopic.php … 2#p1088032, but it didn't helped.
Screenshot from alsamixer:

Have you got any ideas, why is this happening, and where i can find more information about this issue?

So, this might be ignorant of me, but my first guess would be its a hardware issue. Maybe you should try running a live CD of another distro and seeing if you have the same problem? If you do, then its your speakers, not Alsa.

Nope, on windows, on Ubuntu 10.10 liveCD, and my previous OS (Ubuntu 10.10) it has been working fine.

Well, on the bright side, that means its a software problem, which is "easier to fix." On the other hand, we still don't know what the problem is. It might be a drivers problem, then. Have you gone through the configuration listed in the Arch wiki?

Yes, I've completed this configuration procedure.
ATM ignoring Hedphone, Speaker and PCM in volume slider helped a bit (setting "volume = ignore" in files: /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common, /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf, /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf in sections: [Element PCM], [Element Speaker]).

I've discovered that the main problem is that amixer is slow, he does not change the value properly in time. When I'm running amixer from terminal, everythin's ok, but when it is being run from keyboard shortcuts the problem appears.

Is there any way to adjust volue without using amixer, or speed it up?

I suppose you could write aliases in bash and just always control the volume by the terminal, but that seems quite clunky. I'm honestly surprised that shortcuts would be noticably slower... I notice in your screenshots that your balance is indeed off... Perhaps as a temporary fix, whenever you notive the problem, open alsamixer and press "B" to get the mixer to balance your sound.
