Comment:
this is especially annoying since kmix seems to choose by default the
first mixer channel, which is "Bass" at my first soundcard (pointless to
say that this is stupid).

Additionally kmix does not respect alsa settings, I have an .alsarc
which sets another soundcard as default, but kmix always uses hw:0,0
instead of the new default. But it remembers the master mixer I chose.

In $HOME/.kde/.share/config/kmixrc something like
MasterMixer=ALSA::VIA_8235:1
MasterMixerDevice=0
sets the default mixer, and in fact kmix uses the value in "MasterMixerDevice", but doesn't change the controlled soundcard to the one specified in "MasterMixer". At least one is able to set the default mixer of the first soundcard. 

There are a lot of files named like "kmixrc6ZPaia.new" in
$HOME/.kde/share/config/, this looks to me that if KDE restores a
session during login, some of these config files is used instead of the
main one (but I may be wrong). Perhaps something with the session
management of kmix is also broken. Since I prefer to start kmix via
$HOME/.kde/Autostart, kmix will use the main config file.
