What settings do you usually use for Reaper on Arch? Have you measured the round trip latency using a loopback audio cable (by playing a waveform, recording it back with driver latency compensation disabled in Preferences, measuring the offset between original and recorded) and compared it to the latencies reported by Reaper?
I am also using Arch. Was thinking of digging into the Linux USB audio driver code to try to reduce USB audio latency.
