[USB-Audio - Avantree DG60P, recording] Duplex is missing

[Marcel Brouillet]

Under pavucontrol, I get four options (see below) : Mono Input, Analog Stereo Output, Digital Stereo (IEC958) Output, or Off. All options work fine (beside caveats below) but I am missing the Duplex mode.

Recording works on Ardour if I set 8kHz sample rate. Other software (Mixxx) refuse to open the input probably because the sample rate (44.1kHz or 48kHz generally) apply to output and input, presumably. Any side answer on this point would be nice too, but my main concern is activating Duplex mode.

This report is close, but different, to bug 2048897 with a different adapter (has same missing Duplex mode, but Loop110 works worse : no usable sound).
