Hi, I'm Bernard. I'm happy to help!
Do you see an X mark on your audio icon? Have you tried checking the audio output of the PC?
Go to Settings > System > Sounds
Under "Choose where to play sound" make sure you choose the correct speakers
Under "Choose a device for speaking or recording" make sure you choose the correct Microphone
Note: If the issue persists, I'd appreciate it if you could provide a screenshot of the audio driver in Device Manager:
-Press the Windows key + X
-Go to Device Manager
-Expand the Sound, video and game controller
-Look for Realtek (R) Audio or High Definition audio
Then provide a screenshot.
