Re: [gentoo-user] mplayer sound issues

["Mike Myers" <fluffymikey@gmail.com>]

Just to keep you posted, if you're still interested;

I migrated to alsa-drivers from using the kernel drivers.  That alone
didn't seem to fix anything.  So, I updated to the 1.0_pre7-r1 version
of mplayer and that seemed to take care of the alsa issue with the wav
files.

I'm still having trouble playing dvds though.  But that's really a
separate issue.
