I'm far away of being an expert, but if I understood something, I hope this
Well, Olivier, I'm probably the one who wrote the notes about the Fast Track
Pro you told. So, as Hans Petter said, there is a quirck to set the
frequency to 44100. I'm not using tha quirck yet, but using
hw.usb.uaudio.default_rate=44100 on my /boot/loader.conf solved the problem
I made some tests with jack, as simple as
$ jackd -r -d oss
And recorded with 2 channels in Ardour, without any problem. I can't
remember how (probably with a qjackctl or ardour option, some day) I
recorded at 48000 Hz (using hw.usb.uaudio.default_rate=44100).
I hope you M-Audio works well.
Thanks to Hans Petter, BTW.
