From my recent experience benchmarking the DAW I'm working on under Arch (ossia-score-git, please check it out ! :D), disabling the intel sleep states and basically every idling stuff (cpupower idle-set -D 0) had a muuuuch greater impact on jitter than anything else I could do. Yeah, looking forward to bringing that to [community] actually! :)
How could 44,1KHz be a recommended sample frequency for a pro-audio environment, while most pro-sumer and professional audio devices work best at 48KHz?
Do you have a source for this ? if anything, unless you work primarily in motion picture sound & music, most sample libraries are recorded at 44100 so you will get resampling fairly often if you're not on 44100. 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]).
