[arch-proaudio] JACK 1: extreme CPU usage (since update from 5.0 kernel)

[Jeanette C.]

Hello David,
I have now installed and booted a realtime kernel, thanks for your repo,
and installed and enabled irqbalance. There's one question however, to
which I can't find a satisfactory answer.

How do I check my soundcards realtime priority. iotop gives a kind of
RTprio as something like be/4, the manual is unclear on that
classification. Well, they don't explain it. :)

Best wishes,

Jeanette
