gksudo, pkexec or Co.? I don't have it installed. Do you need it for
some reason?

I already using scripts for running PA via jack ...
But here it looks like you need root to switch it off :( irqbalance should be disabled?
"Disabling the irqbalance daemon
This daemon is enabled by default and periodically forces interrupts
to be handled by CPUs in an even, fair manner. However in realtime
deployments, applications are typically dedicated and bound to
specific CPUs, so the irqbalance daemon is not required." -

Ok ... BTW what is rtc?
There was RTIRQ_NAME_LIST="rtc snd usb i8042"
And onemore question here ...
I have also PCIe RME card which I would like to use sometimes ... any
chance to give high priority to it?
RTC is for real-time clock, usually completely irrelevant for pro-audio.
I've got a PCIe (tower PC, not laptop) RME card, too.
[rocketmouse@archlinux ~]$ grep NAME_LIST=\"u /etc/conf.d/rtirq
RTIRQ_NAME_LIST="usb snd_hdsp snd_ice1"

For my old mobo I unbound USB ports sharing the IRQ with audio devices,
for my new mobo it's not possible, but the shared IRQ doesn't cause
noticeable effects. Usually I do not use the USB device, but the HDSPe.
Until now I didn't care that the USB ports are above the HDSPe.
I have only 3x USB ports on my laptop :( it confuse me
a bit.
Anyway how can I recognize which one is which?
Trial-and-error and feel free to google. I don't know how to get access
to all USB ports, for my tower PC I'm using USB slot
brackets, https://cdn-reichelt.de/bilder/web/artikel_ws/C610/AK674.jpg .
