Put this in a file /etc/modprobe.d/alsa-base_`hostname`.conf,
because alsa-base.conf will be overwritten by an update.

Hmm, it might be an upstream bug. But this is obviosly "Skype's"
fault which isn't supported from Debian and not an ALSA bug, though.
People want to run bleeding edge apps like skype, mplayer and the
newest soundcards but have no courage to run sid where the newest
hard- and software is supported, almost...

Within the next weeks alsa 1.0.24 will be in sid with fundamental
changes in drivers, libs and utils. You should give them a try,
though.
