OS : Pop!_OS 21.04
Gnome : 3.38.5
Hardware : Intel i7-7700K, 32Gb 3000MHz CAS15, nVidia GTX 1080ti
Audio Interface : Roland Quad-Capture (USB-B)
ISSUE : Device not displayed in the list of Recording Devices on Settings - Sound - Input
Hello folks - I remember that when I last tried Linux Mint about five years ago that the Roland Quad Capture was not well supported in Linux at the time. I am now back trying to use Linux again and while the playback side of the Roland is now well supported, I cannot select it as a Recording device and would appreciate some assistance finding out why.
The list of Output devices does show it properly as "Analogue Output - QUAD-CAPTURE" but the Input devices only shows a 3.5mm jack device built into a soundbar I have.
Oddly enough, however, the Quad-Capture is listed by the "arecord -l" command and I would love to know the reason why I cannot select it.
Output of "aplay -l" snipped to hide irrelevant items...

It is showing in arecord but I would love to know the reason why it is not selectable on the Settings - Sound page. Is there a dependency missing or is it still as unsupported as it was back in 2017 when I last looked?
