Apologies for the late reply, but it occurred to me that perhaps jackd is attempting to use some combination of settings which do not work properly for the hardware for some reason. There should be messages to standard out describing the settings jackd used to open the device. You could either capture those by starting jackd from a terminal, or I believe they should be collected by qjackctl and made available in a separate "logs" tab from the GUI. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
