You want these ‘other sounds’ to automatically lower down during phone calls. So that’s clear… NO to manually muting or lowering the sound volume for whatever it is you’re playing when making or receiving computer calls. Please note that a 'call' in this context means either an audio or a video call made using a communications app installed on your computer such as Skype, WhatsApp, Zoom, Viber, Messenger etc. You want to hear that incoming call loud and clear OVER whatever music you’re listening to, or video you may be watching. However, you sometimes need to make online calls during the day and you don’t want to constantly start and stop your music each and every time you make a phone call. Automatically adjust audio volume during phone calls in Windows 10? Why would anyone want to do that?
