The jack backend manipulates priorities automatically,
using SCHED_RR while playing plus adding a watchdog.

In case you are using the jack backend, you should
not be able to set better priorities manually. Setting
a priority as high as 50 is not useful here. So those
clicks and hums are still going to be there. (chances
are they'll disappear if you use snd-ls instead of snd
though because the player in snd-ls puts all
sounddata on a ringbuffer before processing)
