(Posting for reference because it took me a while last night to find the right answer.)
One of the common recommendations for audio setup on Linux is to pass the kernel parameter "threadirqs" to a PREEMPT-capable kernel.
If using systemd-boot instead of GRUB or GRUB2, do it this way:
As root, edit /etc/kernel/cmdline and add "threadirqs" (without the quotes) somewhere in that one-line file.
Then reinstall the kernel or all available kernels* (or install a new kernel that you intend to be the primary one for music production) and reboot.
Confirm the successful activation of that kernel parameter by running rtcqs (if installed) or with:
cat /proc/cmdline

* EndeavourOS has a script at /usr/bin/reinstall-kernels that will do this, but I don't know if that is specific to that distro or not.
