I'd be interested to hear these comments, because from my understanding,
niceness has a lot to do with audio performance.  Or, more generally, it has
a lot to with the performance of any process.  By setting the niceness of
programs run by users in the Audio group to -19, you are letting the kernel
know that those programs take precedence over most others when deciding how
to allocate CPU resources.  How would this not help performance?  If this is
misguided, then it would definitely be good to know.
