I have a Dell Microsoft computer running Windows 10. This week I lost my internet connection, and it was determined that my modem needed replacement. Once the tech person came and replaced it, it's just been like Whack a Mole trying to get things back to normal. I've solved everything but my microphone. Once everything started with Zoom this year, I pulled out my microphone, which I hadn't been using, plugged it in, and everything worked perfectly. Since the new modem was installed, it no longer works. I can't unmute it, nor can I speak through it. When I do a test, I get the message that they can't find the device. It's definitely plugged in just as before, in fact I never unplugged it. Does anyone have a solution?
