Works just fine here; anyway we cannot fix anything there, report this upstream.

Not nice. As I stated before, this doesn't work on several machines. The fact that it works on yours just makes the point: it's rather configuration problem than just buggy application. In any case, turning on ALSA PCM plugins makes skype work again. It's done by adding the following line to make.conf:

ALSA_PCM_PLUGINS="adpcm alaw copy dshare dsnoop extplug file hooks ladspa lfloat linear meter mulaw multi null rate route share shm"

This line turns on all the available ALSA PCM plugins.
