Can't hear output

[harrispoole]

You need to connect headphones to the USB mic, otherwise audio gets blocked indeed. You can control input gain in the Mixer tab.

Well that was easily answered. Many thanks!

Instead of connecting headphones it obviously also works to unplug the USB mic to hear playback - but it then says disconnecting the USB device while the app is running is not recommended. 

Will that do damage to the mic or the phone to unplug the mic while the app is still open but not recording or anything, or is it safe to unplug it to listen to audio? (I'm aware that I'd need to re-start the app with the USB plugged in if I wanted to record again).

Thanks.
