Support for Nuraphone headphones over USB-C

[amallinson]

Hi

Would it be possible to add support for the Nuraphone headphones over USB. The company sell USB-C and Micro B cables i believe.

I tried the USB C one and only some songs played on the headphones and the others were silent. I tried using the Android built-in driver and they all played fine.

I ran the audio feedback thing from the app and have pasted that below if it helps?
