Yes, get the Skype developers to add proper ALSA support.  If Doom 3
could do it, so can they.

mpg123 is an open source application so there's no excuse for it not to
support ALSA in 2005.

Finally, these questions are all OT for LKML.  Try alsa-user at
lists.sf.net and alsa-devel at lists.sf.net.  Also there's a bug
reporting system, linked from http://www.alsa-project.org.
