also don't
forget to add this to /etc/security/limits.conf :
@audio - rtprio 78
@audio - memlock 400000
@audio - nice -10
These are already there:
# audio facilities:
@audio - rtprio 95
@audio - memlock 512000
@audio - nice -19
better or worse?
that depends.
your file allows the audio group to set/get an rt-prio of up to 95,
which may not be required.
if you have about 2GB of RAM or more, you might want to increase memlock
