I have the same computer and I'm having the exact same problem. Any help fixing the issue would be appreciated. Thank you!

Have you received any update for fix?

I have the same laptop, and this has been an issue since Day 1. I have been told that I cannot get a refund on the laptop. I have sent the laptop back for repair, and it was returned to me with the same issue.

I have another Dell laptop that does not experience any issues. I am very disappointed in the quality of the audio components, and in the support I am receiving from Dell.

My issue is resolved.  A lot of things were done - run updates (again) via Dell Command and SupportAssist, disable the mic on my headsets and use the built-in mic on the laptop, wipe/rebuild (did not do!!), roll back the audio drivers.  I have done updates since then too and I also bought a different headset but I'm not experiencing any audio issues anymore.  All the headsets I used when I had the problem were bluetooth (no dongle) or wired - plugged into the sound jack.  This new one has a dongle so, while it's bluetooth too, it's seen as USB.

I'm experiencing the identical issue. Is there a way to receive support? 

Thanks!

I am having similar problems with the built in Microphone. When I test it within the system it works fine. Any third party app doesn't work well, the microphone cuts in and out.

I've spent many hours, installing drivers, messing with the various settings, I did a full wipe of the OS, done testing with Skype, Hangouts, Zoom, Google Meetings... 

Dell at this point says its not a hardware issue that its the third parties. But every app?

Any help would be appreciated.

thanks

edxply had the resolution for me.

In the MaxxAudioPro Waves app (I didn't know I had this), choose the icon/tab for voice (in the upper right, looks like a top down view of a person at a computer)  Turn/toggle off the button on the left below the tab icons (terrible UI) and that's it!

You are my hero! Thank you! I can't believe it was this simple.

One call I had with Dell was 5 hours and 9 Minutes of testing, reinstalling, and ridiculousness.

Seriously,

Thank You!

We have 2 XPS 13 7390 with this issue (only wenn using Zoom however, not wenn using MS-Teams). Switching off voice in MaxAudioPro (wasn't aware I had it) does the job!

I'm having this exact problem. Especially with zoom. I bought the laptop to use for zoom conferences. I would strongly advise people against buying this laptop since support is poor and without a microphone work is impossible. Has anyone managed to solve it?

Switching off voice in the MaxAudioPro app (you can search for this on the computer) actually works. I can't believe that the technical team didn't suggest that. Thanks to you in the forum who did. 

Thanks for this post! The cure for the mic cutting in and out (happening per people in my zoom calls) was also shutting off the microphone "helper" in MaxxAudio Pro. I was getting berated and was asked what kind of computer I bought 4 days ago so people could avoid it... embarrassing and frustrating. I think the intent is that the software will better block out unwanted sounds but it is too aggressive and reacts quickly resulting in the cutting in and out. Just looking for microphone settings in Windows doesn't bring up the Maxx software options so I was getting ticked. If I can't find a decent reason to have it I'll just uninstall the program.
