XPS 13 7390 Microphone Not Working

Same problem, same machine I just bought.  Dell has told me it's a software issue and they can't help unless I pay for their software support.  Zoom has told me their engineers are working on this as a known issue.  I expect there to be some driver update that comes along and fixes it eventually.  Until then I think we're stuck, either using phone audio, the zoom web client (mine works with that!) or finding another workaround, eg using another device to zoom.

I just bought this laptop in August and whenever I try to zoom or have a video call on this laptop- the microphone doesn't work well. It fades away as soon as I finish my sentence. I am a university student and will be needing this laptop for the coming three years.

Kindly help

Hello. Could you private message us the service tag or the express service code so that we can assist you.

Changed my laptop over twice in the last 4 weeks for new replacement. Same issue. Looks like i have bought a real lemon

Same issue - Same model laptop purchased AUgust 2020. This fade in and out is a problem for both Zoom and Google Duo, so seems to be problem with computer not the apps. 

I was having the same problem and found this solution on another thread. It solved the problem for me. Hope it helps you.

Good luck.

That worked! Thanks!
