Public bug reported:
I purchased a USB dongle that presents to the system a sound device (and
hides a Bluetooth or proprietary RF connection to a headset).
https://fr.shokz.com/products/dongle
When connected, I only get to choose between two playback profiles in
pavucontrol (see below). There is no input profile nor the Duplex that I'd
expect.
Moreover, when I play some music, there are a few low cracks, music is barely
recognizable for 2 seconds (if anything) and then fades out completely.
Sound is perfect with the same headset in Bluetooth mode A2DP or HFP, but I
expected better latency with the proprietary USB dongle.
