could this community give me some advice on making the Lynx Hilo USB
aduio device work on Linux? Lynx says that the Hilo is USB audio class
2 compliant, and the driver works with OSX and IOS. My Hilo works well
under Windows, but I was hoping that "UAC2 compliant" would also mean
Linux.
The device is recognised at start-up, and snd-usb-audio is loaded, but the
following error messages appear on the console:
[Sep21 22:05] usb 5-2: new high-speed USB device number 2 using xhci_hcd

After disabling the other sound cards on my system, I have run alsa-info.sh,
and the output is attached to this message. Lynx's Chief Engineer has looked at
the above output, his response was:
"I saw nothing in the log about channel numbers. Just clock sources, which to
the Hilo-USB mean absolutely nothing since it should always be on internal
clock anyway."
Any help that members could provide would be greatly appreciated.
