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 Even https://aur.archlinux.org/packages.php?ID=25441 is outdated.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 Usually outdated rtirq scripts don't work.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!
