Hi Vaibahav5555,
Welcome to Microsoft Answers.
We would like to get a better understanding of this issue so we can better assist not only you but other
users with similar problems as well.
a)
Do you have any other application that is associated with the sound (e.g. realteak etc)?
Uninstall other applications that are associated with sound and check whether the problem persists.
Method 1:
While you are using your PC to place or receive calls or while you are playing games which use PC calls feature, Windows 7 automatically reduces the system volume without even
asking you.
Actually it’s a new feature introduced in Windows 7 which can be disabled using following simple steps:
1. Open "Sound" applet from
Control Panel. You can also access it directly using "mmsys.cpl" command in RUN or Startmenu searchbox. Or right-click
on Speaker icon present in system tray and select "Playback devices" or "Recording devices" or "Sounds" option.
2. Now go to "Communications"
tab and check the option "Do nothing" and Apply it.
3. That's it. Now Windows will no longer reduce the system volume.
Thank you and Regards.
