IIUC there is _no_ drawback when using -n >2, if there would be a drawback, it would have been mentioned in the man page?! OTOH the default rate is 48000 Hz and for good reasons it definitive is the rate used for studio productions, but there's no hint not to use rates < 48000 Hz ;). It would be nice if you would share information, I guess this is what lists are for, it's not a battle ;). Unlikely that the Arch jackd manual page is incomplete, but I can't find further info there. [1] ALSA BACKEND OPTIONS -n, --nperiods int Specify the number of periods of playback latency. In seconds, this corresponds to --nperiods times --period divided by --rate. The default is 2, the minimum allowable. For most devices, there is no need for any other value with the --realtime option. Without realtime privileges or with boards providing unreliable interrupts (like ymfpci), a larger value may yield fewer xruns. This can also help if the system is not tuned for reliable realtime scheduling. For most ALSA devices, the hardware buffer has exactly --period times --nperiods frames. Some devices demand a larger buffer. If so, JACK will use the smallest possible buffer containing at least --nperiods, but the playback latency does not increase. For USB audio devices it is recommended to use -n 3. Firewire devices supported by FFADO (for‐ merly Freebob) are configured with -n 3 by default.
