If you have the directory /etc/security/limits.d/ then create a file
in there called audio.conf and put the following in it.  Otherwise edit
/etc/security/limits.conf and add the following lines.

@audio          -       rtprio          80
@audio          -       memlock         51200
@audio          -       nice            -10

Log out and log back in again, then type "ulimit -r".  That should
output the number 80.
