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.
