At this point something goes wrong on your machine and jack quits, this is what normally happens: configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods ALSA: final selected sample format for playback: 32bit integer little-endian ALSA: use 2 periods for playback Cannot use real-time scheduling (RR/10)(1: Operation not permitted) AcquireSelfRealTime error Then at this point jack crashes. @tiwai Can you shed some light on what's going wrong here with Martain's alsa?
