[LAU] Hardware Soundcard - MOTU 624 AVB Working with Gnu/Linux - Debian 8.7

[Anders Hellquist]

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.
