I used an external mic last night and it was fine. Does that mean that it isn't a hardware problem? I have yet to try using the sound recorder. I'll be sure to update when I do so.

Hi,

Thank you for reaching us.

Easiest step we can try here is to use "Sound Recorder"

Click start, Search for "Recorder" , Open the app, try recording something and playing it back.

Also if you have an external mic, you may try using that to confirm if it is a hardware fault.

Thank you
