All audio devices I know automatically are set to the sample rate set by alsa, 'jackd -d alsa --help'. No, the latency will differ for different sample rates: 512 samples / 44.1 kHz = 11.609977324 ms 11.609977324 * 2 = 23.219954649 ms ≈ 23.2 ms 512 samples / 48.0 kHz = 10.666666667 ms 10.666666667 * 2 = 21.333333334 ms ≈ 21.3 ms Higher sample rate = more data at equal bit depth. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
