Hi,
ps -elH
will give a listing of all processes and their priority settings. The chrt
tool will also allow you to change scheduling priority as well as your
scheduling policy.
Find the process ID of the IRQ thread used by your sound card from the
previous command, and try using something like:
chrt -f -p 80 [process ID of the IRQ thread]
(and remember that the number scale listed by the ps command and the chrt
command when referring to priority levels are not the same. You are setting
the priority level of IRQ thread to "80" in chrt, and should show up in ps
as -21)
Another helpful tool you might want to insall is htop.
