If Windows detects a telephone call being made by your computer, it can drop the volume by a set amount. This drop can range from a 50% drop to a total muting of all other system sounds. What’s actually happening here? First of all, it’s good to realise that Windows has an option that handles this. So, before you complain to Skype about the lack of options, give these steps a try and see if they work. This kind of behavior can be very irritating, especially for users that go through Skype’s options and settings and find no way to turn it off. There’s a good reason for this: the audio drop has nothing to do with Skype whatsoever! It’s built in to Windows itself and isn’t an official Skype feature.
The actual Skype call will be at normal volume, but everything else will seem much quieter. As soon as a Skype call starts, however, your computer’s audio volume takes a sudden and highly noticeable drop. You’d can open Skype and message people without any problems.
Before a Skype call starts, your computer’s audio levels are totally fine. When making Skype calls on a Windows machine, you may have come across a very annoying feature.
