I am having quite the time attempting to adjust threadIRQs for my USB interface for audio recording to prevent audio dropouts and optimize CPU usage. Currently using Xen and an Intel 12th gen CPU (I suspect Intel’s Big-little architecture is secretly to blame for my audio issues but I want to do my due diligence)
The last time I did this for an OS was Manjaro in 2020 - I cannot find where that configuration file is with my Garuda setup. Anyone able to point me at where I would go to adjust those permanently, rather than adding a line to the config at boot time?

Garuda (2.6.26-1):
System install date: 2022-09-16
Last full system update: 2025-01-01
Is partially upgraded: No
Relevant software: NetworkManager mkinitcpio
Windows dual boot: No/Undetected
Failed units: mnt-bulwark.mount
I’ve had good results with this guide.
Some of the config files will be in different places with Garuda, but all the main points are covered.
A Pro Audio Tuning Guide for Arch (and other Arch-based distros)
Also, one thing I learned as a noob is that if you want to use an audio interface for playing live instruments in real time like guitar, you’ll want to select “ALSA” for your audio device/mode in your DAW.
