OPZ not monitoring my Samsung S10+ anymore via USB :'(

Hi fellows,

what I’m trying to do here, is to monitor my S10+ playing some synths or stuff, in my OPZ through USB, via the provided USB cable.
It used to work fine, with the cable plugged as master in the phone (USB A-C adapter plugged in the phone), but then suddenly, my phone crashed and rebooted, and since then I’m not getting any sound in the OPZ…
Thing is it works like a charm with my Windows 10 laptop, so I believe this has to do with my phone. I have no idea what I can do from here to solve my issue…

Any thoughts?
