Question / Help Mic randomly muted during stream and now doesn't work

[ElPlaza]

Hi! I have a problem with my microphone: during a stream the mic muted by itself and now doesn't work anymore. The red bars of the audio level in the main page are all filled and in the "noise reduction" tab of the configurations it seems to work. PTT is not enable.

Thank you in advance
