Sounds like time for "lsof" to see what is keeping the sound system
busy. Beyond that, while Christian Marillat does an excellent job both
on the packages of the archive he maintains and the many packages he
maintains in the Debian archives, mplayer (and its variants) is
something that I find requires a local build from source to *really*
work reliably on any computer I've worked with it. Download the source
from http://www.mplayerhq.hu, untar it and from its lead directory, run:

./configure --help | lpr

after which you can run debian/rules with the appropriate flags for the
type of system you have. It will work much better than what anyone else
can package because mplayer is still very machine specific.
