Hey'
Sound is very distorted and buzzing with alsa-1.0.1, and current cvs
(pserver) on my soundblaster-128. The default slackware-9.1 (alsa-0.9.6)
did not have this problem. I'm using linux-2.4.24 and the oss es1371
driver sounds OK.
Don't hesitate to ask for more info, get me to try fixes, etc - anything
to get my alsa back ;-)
