I never quite understood what was supposed to be bad about replying to one's
own post.. :)
Ok, you have not done any irq priority tuning.. Try
setting the IRQ-10
process [your emu10k1] to prio 90..
I'm not sure what I'm doing here. I presume I need to use chrt to change
the priority, but am not sure of the correct syntax. The current pid for
IRQ10 is 940.
Could you give me a line that will work for this pid, as the man page is
pretty hopeless with no examples, and about 3 hrs of googling turned up
virtually nothing.
Many thanks.
Nigel.

I'm getting on
Fedora 7.
With soundcard irq prio at 90 [not shared with any other device], Jack prio at
70 and all other irq prios at default 51?
Then it's either an application bug [are you running any applications]? Or a
bug in the emu10k1 driver. Or in jackd, though i suppose that's rather
unlikely..
Will that change of priority I've made for the soundcard on the current
pid, hold after a reboot?
Nope.. It will be started with the default prio again. Have a look at the
rtirq script or fiddle your own initscript. Most distros have some "local"
init script where you put that command..
