I purchased a Bluetooth headset (Belkin SoundForm Adapt). In the beginning it worked normally on my laptop. Now, out of the blue, it seems that whenever the microphone is activated, the headset is "muted" (no sound is passed to it so i can't hear the remote party in a call, they hear me fine though). I have also connected a Corsair HS65 Bluetooth headset on the same laptop and that seems to (still) work properly.
Please note that other apps (Skype, Teams) work fine with both headsets. Only Zoiper has an issue with one of them (the Belkin one).
I have tried setting it as default media & comms headset in windows, tried various combinations within Zoiper but no luck. Anyone has any idea what might be happening or what else should i check?
