Hello!
Before I throw solutions at you I just need a little more context.
Are you having this issue in a specific program like Microsoft Teams?
I would also like to know if the sound on your computer works fine for other things, like watching a video online or hearing regular system alerts.
Lastly, how are you trying to listen to them? Like are you using built-in computer speakers, a headset, or something plugged into the audio jack?
Just reply back with that info and we can figure out the next step.
