So,

Few days ago my Kraken 7.1 v2 USB microphone stopped stopped working in every application except for Razer Synapse 2.0. When I press the button on mic itself, it appears to work (red light appears/disappears), same when configuring it in Synapse. It's not detected even by Windows Settings itself. I tried reinstalling Synapse, checking for newest drivers, turning it on in various magagers etc., but nothing changed. Any ideas? I have 64-bit Windows 10.
