I'm a beta tester for a synth trying to troubleshoot a new Class Compliant
USB IO board. It uses UAC2 to stream 192k stereo, or 12 channels at 48k or
96k. The snd-usb-audio module loads when I connect the device and it looks
to be identified correctly under /proc/asound, reporting its output format
as S24_3LE, which I believe is correct.
With one exception, though, any stream I capture from this input - I used
arecord, Audacity and Jack (via alsa_in and routed to my soundcard output)
- contains mostly nulls with what looks like the occasional valid data
point, every hundred or so samples. (I haven't counted them.)
The exception is Ardour using the ALSA, which captures the entire 12
channel stream flawlessly.
What might Ardour be doing to set things up properly and how do I replicate
this such that the rest of my system does it, too?
(I'm running Ubuntu Studio 16.04.1 LTS with ALSA Version k4.4.0-45 on a
Thinkpad X230.)
Thanks
BN
