What a nice surprise Claus
I thought it will never be fixed because you said noone is working on it since 2 years ago.
After installing pulseaudio alsamixer won't run because of this error
MLD> alsamixer
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_ctl_pulse.so
cannot open mixer: No such device or address
I got that file from libasound2-plugins package, now it works.
Icq sound settings also works as it used to crash if you select it.
But i can't listen or record voice messages, i think there is a problem with sound redirect, as it's redirected to the internal sound card not the USB sound card.
Regarding Skype, i tested the Eco /sound test service, USB microphone doesn't work.
Do you have USB headset in order to test it?
