Please help, I'm on newrow (It's like zoom) and it keeps saying my mic is muted. Or whenever I try to talk to people or alexa, they still cant hear me. My volume is up, everything is fine. It's just that I want to know how to unmute it, also if this helps, last night my dog stepped on my keyboard and clicked random buttons then right after, a button appeared on my screen showing like a microphone with a line crossing it out.
