Hi Patrick,
The IRQ number I don't believe has to do with priority much anymore.
What you want to be higher is the RTPRIO number. It looks like
neither of these are really prioritized... I remember rtirq being
pretty smart and being able to automatically grep for your sound card
IRQ and adjust the rt priority.. in this result, have you already run
rtirq?

I have rerun rtirq after adding the wifi card to the conf file and found
that the wifi card is set to 70 while the snd card is set to 85.
There are a few interrupts in between for the usb and the video devices.
What I am seeing is a massive spike in xruns when running a gui app taht
connects to jack (even qjackctl) but nothing when playing a track from
the commandline ie mplayer -ao jack. This only happens if the wifi
module is installed. Without it there are no xruns for days.
Unfortunately the snd the video device are on the same irq.
Does anyone have an idea for why the gui system would become unstable
when the wifi device is added?
Cheers.

I see this
result. Sound card is irq 16 and wifi is irq 17. Does it mean the
wifi card has a higher prio than the sound card?
CMD RTPRIO
[IRQ-16] -
[IRQ-17] 50

Hi,
If I'm running rtirq from /usr/src/rtirq folder will it pick up the conf
file in the same folder or does it have to be in the /etc/ folder?
Also how can I check the existing irq prios for the devices prior and
after running the script?
Cheers.
