Very Low sound output ONLY during Zoom meetings.

I have Windows 11 on Dell Inspiron 15 3530 laptop with latest updates on Windows as well as Dell. Only during Zoom meetings the sound output is very low. Even at 100% volume the sound is low.

First I tried by uninstalling the Zoom app then reinstall it again. NO CHANGE. 

Then downloaded the Realtek Audio driver from Dell web site, installed it. NO CHANGE.

Tried different suggestinos on Zoom website. NO CHANGE.

Anyone has similar issue?

Any solution?
