The regular timer should be automatically set to group audio during
startup, run

$ ls /dev/snd/timer -l

to check this.

Hpet needs to be set by you for startup. Or in a terminal emulation run

$ sudo chgrp audio /dev/hpet
$ sudo chmod g+rw /dev/hpet
$ sudo modprobe snd-hrtimer

to set it after startup.
