[arch-general] [Information] Outdated rtirq scripts don't work with current kernel-rt

[Ralf Madorf]

Hi :)

just an information, since rtirq doesn't fit to the current kernel. Even
https://aur.archlinux.org/packages.php?ID=25441 is outdated. I got it
from the archaudio repos. This cause that settings aren't working.
Here a RME card seems to be loaded as the highest priority audio card,
but the status shows that it isn't [1]. Using the current version
everything is ok [2].

When Rui edit rtirq, than he does this for good reasons. Usually
outdated rtirq scripts don't work.

I'll try to build a package using abs tomorrow.

Cheers!

Ralf
