[alsa-devel] Bizarre ATI SB450 behavior

[Tobin Davis]

Please download alsa-1.0.15rc1 from http://alsa-project.org or a daily
snapshot from ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver/ and
try it.  If you are still having issues, please run
http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh and post the
link that it creates.

Thanks,

Tobin
