Hi I am using suse 10.1 with amarok. when I play mp3s, sometimes the sound gets very scratchy and distorted. also whenever I move a window, or resize, etc. the sound becomes scratchy. I noticed this after I installed xgl. Can anyone help me? thanks.

there are lots and lots of little tweeks you can do to get sound better
lets see if i can remember some
this stuff involves just messing with it til you find the combination that works
first thing might be to denice Xorg with
renice 0 -p `ps -C Xorg -o pid=`
or
renice +1 -p `ps -C Xorg -o pid=`
next do
lspci -v
find your sound card or controler and notice the bit labled latencytry increasing that a bit with a command like
setpci -v -s '04:08.0' latency_timer=48
where '04:08.0' is changed to the proper thing of your sound card
this can go pretty high like 225 or so i think
setpci takes the number you give as only a sugestion most of the time.
next thing to do is began to mess with your ~/.asoundrc
make dmix plugin and begin to toy with new values for
period_time
period_size
buffer_size

you can lookup how to make a dmix lugin on the web to get you started
