Re: [LAD] timers

yeah, I have added a few things in a startup script. Among other things, I have:

chgrp audio /dev/hpet
echo 1024 > /proc/sys/dev/hpet/max-user-freq
modprobe snd-hrtimer

The modprobe may not be needed anymore as my kernel is using hr-timer by default. I wrote this script quite some time ago and forgot about it :)
