I have no idea if there is a linux driver as the manual only mentions
Windows and Mac OS (but no driver required for the latter)
So this is what I would try if it were mine.
Your welcome to try at your own risk :)
Plug it into the a pCP rpi usb 2 socket
Reboot the rpi, go to the Squeezelite Settings select USB as Audio
output, save and follow the instructions.
If you have no output to select that looks like the device, just reboot
Open a Terminal (user tc, password piCore) and type
Code:
--------------------
lsmod
--------------------
You are looking for a line with usb_snd_audio.
This is an example of an Apple USB headphone plugged into a pi running
pCP
Code:
--------------------
tc@pCP:~$ lsmod

It is not recognised.
I then plugged it into a rpi running the raspberry PI OS Buster Desktop.
Rebooted and ran lsmod, this is the result

and it is working.
If your device does not work in pCP but does in Raspberry PI OS Buster
Desktop
Then if you ask paul- and show both the lsmod results, he may be able to
integrate it into pCP (I say Maybe!!!)
Sorry for such a long post :p
