FWIW, just finished a little test... I recorded a 3 minute "click track" of a metronome using the two built in mics on the R16. I then plugged my playback device into two tracks on the R16 and overdubbed those two tracks...and repeated the process 4 more times, each time playing back the previously recorded tracks while re-recording them onto two more tracks. Theoretically, this should bring out any sync problems, but there is no discernible difference in the beats when playing back all 32 tracks. Would I trust this setup for sample-sensitive work like film scoring? Probably not... but I really don't think it would be an issue for producing traditional music tracks. I am sure the mileage varies with different equipment, but after a couple weeks of tinkering, I haven't experienced any audible issues with drift...nor have I had a single xrun in JACK. Anyhow, back to the original topic. As it stands, JACK starts with the R16 in "playback only" but tries to set it at 32 bits -- just as it did with the recording before the quirk. If I start it in full duplex, JACK starts fine but then dumps a bunch of xruns and crashes when I start to record. So I think another entry in the quirk that explicitly sets playback at 24 bits should do the trick. -- View this message in context: http://linux-audio.4202.n7.nabble.com/re-Zoom-R16-tp87487p87956.html Sent from the linux-audio-user mailing list archive at Nabble.com. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
