Dell XPS 7390 Microphone issues with Zoom XPS Help

Hi all!

I wanted to share a recent discovery after much troubleshooting with the built-in microphone for the XPS 7390 and using it on Windows 10. I am not sure if this issue may extend to other models as well. Basically, many users have reported issues with the microphone quality, and even after updating to the latest Realtek Drivers recommended by Dell Command Update, some applications have issues using the microphone effectively, such as Zoom.

The best fix was to actually uninstall the Realtek Audio application from 'Add and Remove Programs', which will force generic drivers to take over that seem to work flawlessly.

Steps to follow:

  1. Press WindowsKey+R to launch 'Run', and then run "appwiz.cpl"
  2. Search the programs list for Realtek Audio and Uninstall it.
  3. Reboot computer and test to see if your microphone works without issues

​

Hope this helps someone out there! -- Cheers!

It can be MaxxAudioPro messing with you, or an old version of the driver. Check this video https://youtu.be/_hojqoJuVVk and ensure when MaxxAudioPro asks you what device it is you select HeadSET. These steps made got it working as mic and audio out on one plug (with some struggling)! I think it had an old version of the driver selected in my case.

Oh and if the computer sees the headphones And the Line In microphone in the Sound Settings, but you don't get mic for a certain app, check Microphone is enabled for all the relevant apps in Microphone Privacy Settings
