Well, if you're looking at professional studios, they don't record below a sampling rate of 96kHz usually. To get that kind of throughput stable might require quite some experimentation depending on your hardware. That is to say: I'm also not up for adding a specific preset layer to Arch. Acquiring realtime-privileges and enabling the user to tune his/her system is much more viable, as the exact implementation will be very diverse and depending on the hardware or the user's software. Or as Ralf said: Best case, you won't even have to change anything at all. However, I think that we can and should improve our relevant wiki entries (e.g. [1]).
