Bug Description
Binary package hint: alsa-utils
Hello,
after upgrade to Lucid I encountered a bug in amixer:
"amixer sset Master playback 2dB-"
for example sooner or later decreases the volume for front left channel too much, thus de-centering sound output
Here are my versions:
Kernel 2.6.32-21
alsa-utils 1.0.22-0ubuntu5
Soundcard Creative Labs SB X-Fi
Take a look on the attachment how it exploits. You will see its diverting with dB and with hardware values and it is really arbitrary. Of course I checked other values than "1" as well.

Just found this bug https:/ /bugs.launchpad .net/ubuntu/ +source/ alsa-utils/ +bug/557352 and first I thought this could be the same for me ... but it isn't.
To sum up:
alsamixer is working for me perfectly
amixer is working as well with the only exception of decreasing too much with simple control
