No sound with Bluetooth device

You can check if your Default Recording device is the headset.

It’s a quirk of Bluetooth due to its limited bandwidth: once you activate the microphone of your Bluetooth device, it has to switch its output to lower quality (the headset one) instead of normal stereo output (the headphone one).

To avoid this, set the Default Device and Default Communications Device in the recording tab to a standalone microphone or a webcam (which usually comes with a microphone).
