Shouldn't have to, should be in group audio by default.

Any hints are welcome!
edit /etc/rc.local and add a line before the exit like:
echo 3072 >/sys/class/rtc/rtc0/max_user_freq
Also, may not be needed here but recommended for other apps, edit the last
line of /etc/sysctl.d/50-ubuntustudio.conf to uncomment:
dev.hpet.max-user-freq=3072
We have been testing this and had been unable to see any difference with
it enabled or not in MIDI jitter etc. I am not sure if there are downsides
to setting these (more cpu usage for example), but personally I would give
up cpu usage for better sound.
Please let me know if this helps and I will make it the default.
