I’ve finally managed to get my Mixpre 3 to work on linux.
It’s undelicate… but it seems to work at all sample rates, 2 in 2 out.
- Launch Ardour session (until sound settings) or qjackctl, MixPre connected.
(you have to configure those, even if they fail, to be ready for the last step)
- Switch off the MixPre
- Switch on the MixPre, and as soon as it’s on and ready,
- start the sound/session on ardour or start jack.
AVlinux MXedition (great distro by the way).
Connected by thunderbolt3, usb-c or usb-A.
5.9.1-rt20avl1 (but I had other troubles with this kernel, try for yourself)
MixPre firmware: 7.10
Still need to switch off/on everytime I stop jack, ardour/, or change samplerate.
