I had successfully set up my QC via a USB cable straight into my Android, using it as an audio input for the SOLO app (the Tom Quayle one people may be familiar with). It now isn’t working (following firmware update) for some reason and I am really confused. I have tried everything and this is really frustrating!

May be you have to set audio to usb again.

Did you find out what was the problem? I can’t get this to work with my Samsung S22.

I also have a USB-B to USB-C cable. I did not try with the SOLO app though…

Is there a better thread to discuss this? I have a usb B to usb C cable and my phone’s getting zero input although it’s recognized as an external mic 🎤
