Interesting, is there any reference about whether the alsa interface provides a logarithmic or linear values? Do you know if there is a special case for certain sound cards? If alsamixer handles this correctly it may be that the alsamixer code is the documentation. > I DON'T use PulseAudio and DON'T want to use it, because PA is a > totally useless Lennart creation, wrapper around ALSA.

I've added the forward information so if the bug state change we get noticed of the update. > Both machines on which the bug does reproduce run Debian unstable i386, both > aren't a fresh installation - I continuosly upgrade them since debian 4.0 > etch.

Are you able to revert the issue by installing libasound2 1.0.27.2-1 ? If that's the case a bisect might be productive.
