Bug Description
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:/
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.
