Re: Hardware Soundcard - MOTU 624 AVB Working with Gnu/Linux - Debian 8.7

Could be but the device remembers the sample rate and everything else  between bootups and the display is showing 48k before I hit start in cadence (or qjackctl) so from my point of view, sample rate change does not occur..

I don't think waiting before launching jack helps but I can try that and see if it helps.

That seems to be a function of the device taking a noticeably long time to switch sample rates and be "ready for action". If JACK changes the device state as a part of the startup, it takes a while before it is actually ready.

Ok, the only quirk with my setup that others have experienced too according to Ardour forum threads is that I often need two to four attempts to start jackd (actually using cadence in kxstudio to starti jackd) but when successfully started, it has never failed.
Sometimes it starts on first attempt and sometimes I need more than 5 but usually on second or third.

I hope you can figure out whats causing the unreliable behaviour on your end.

I got mine to work (kernel 4.9) but it seems a little unreliable and may have needed to be used on a MacOS box first. Still trying to figure out what causes the lack of signal at the CPU. Certainly not caused by config changes on the MOTU itself.
