Randomly, or at system sound (usb connect for example) Windows 8 lowers the volume of all other sources. (Same problem can exist on windows 7, just look online).

This is happening because of the "communication detection" made to detect phone calls and then lower volume. But in my case it happens all the time without reason as if windows always considers myself in a call.

Do any of you have the same problem? is this a driver issue or a windows issue? I know this has been posted many times but they usually just tell you to turn off the setting above. I'm looking for an explanation or a solution :).

Thanks for your feedback and ideas.
