They can't hear me

[tgva]

Hi, after using Zoom perfectly well for years now, all of a sudden nobody can hear me. I've checked microsoft access to the mic which is fine and I've tested the mic on zoom which again is fine. I can hear everyone else perfectly but they just can't hear me. I've uninstalled and used the Zoom download, no luck. I've uninstalled and used the Microsoft app and still no luck. Please help anyone, this has me flummoxed 😞
