maybe it would be of general interest, that we are using a rme-96 PST (or was it PSD, stup abbr) interface (that's the one with 8-tdat-I/O + 2 analog I/O + spdif I/O)

hi all!
what is the lowest possible latency that anyone got under linux ? with alsa-0.9.0b4 + kernel-2.4.3(+ low latency patch by a.morton) we are only coming down to 982 samples (which is almost 22.2 ms under 44.1). this works for "-frags 6" decreasing the fragsize even more, will produce knacks, unless you constantly move the mouse inside the pd window (seems like a tool for live-gigs...)
what exactly does the "-fragsize <n>" option mean ? anytime we changed this parameter, it behaved the same (and very badly indeed), meaning 4210 samples of latency and knacksing all the time, no matter which fragsize we choose.
