Why do I get distorted audio when using my Zone Wired headset or Zone Wired earbuds?

Distorted sound when joining a phone call is due to the custom driver, and uninstalling it should fix the issue.  

Note: Once uninstalled, you can use other functions except Equalizer on Logi Tune.

Please follow the following steps to uninstall the driver:

1. Open the “Run” dialog box by pressing Windows + R

2. Type devmgmt.msc

3. Click OK.

4. Scroll down to Sound, video and game controllers > Select the custom driver for Logi Tune on Desktop (For example,Zone Wired) > Right click and select Uninstall device.
