Hm, I aware of realtime-lsm, but as a matter of fact, this module seems incompatible with our stock-kernel configuration, so it is not an option for the standard repos. Since Archlinux is not an Audio specialized distribution, this prolly won't changed so soon.
I could try to rely on damirs --mm kernel, but this one gets broken from time to time(which is an upstream issue and not damirss fault). So this can't be change easily :(

There is a reason I filed this under documentation. Realtime capability is a rather special need: you don't need it to listen to MP3s, or even to play around with apps like Rosegarden. The issue is mainly for people who are serious about creating music. So I see nothing wrong with the distribution providing just basic audio capability, and outputting a message explaining how to get better performance--as is the case now. The problem is *what the message says.* Setting apps suid root is presented as *the way* for normal users to get realtime capability; yet there is another, almost certainly better, way, and we should be recommending it. So people will have to compile their own kernels. Anybody who can't handle that probably can't handle Rosegarden either.
