Windows 7: Windows 7, Closing Laptop Lid causes volume to automatically reduce

Windows 7, Closing Laptop Lid causes volume to automatically reduce


Just having a weird problem with Windows 7. When I am using earphones or my laptop speakers and then I close the lid on my laptop, it causes a great reduction in the volume of the sound output automatically.

While the laptop lid is still open, the volume on all programs remains normal.

However, when I close my laptop lid, it seems Windows automatically reduces the volume.

Let's say I put the volume on my laptop to 40/100 units in the sound mixer. All programs I am using are set to use the volume the sound output device is using, so everything else is also at 40/100 units, including Media Player Classic.

I am usually using Media Player Classic to play some FLAC music. I usually have earphones connected, but this issue recurs without them as well.

When I close my laptop, in about 2 seconds the sound volume will automatically reduce to 5/100 units in the Volume Mixer in the taskbar. This sound reduction also only applies to the program I am currently using to play music (e.g. MPC or iTunes, the two which I've tried so far).

After re-opening my laptop, I check the Volume Mixer and it shows only MPC or iTunes sound output is reduced. The system device speakers will still be at 40/100 units volume.

This is really frustrating, because I like to turn on some music, and then close my laptop so I can study, but I find I have to constantly adjust volume, because Windows is deciding to automatically adjust the volume for me... which I simply don't need... I understand how it can be helpful, but for me it is just a nuisance.

This is what the Volume Mixer looks like just after starting playback in MPC:

This is an example of what the Volume Mixer from the taskbar looks like after I close and then re-open my laptop lid:

It just shows MPC reducing volume, while all other volumes which aren't outputting anything remain at the normal volume I set before closing the laptop lid.

If anyone could help with this issue, it would be greatly appreciated

I was able to resolve this by the following:

Right-Click the sound icon, and click "Playback Devices". There should be a tab that says "Communications" on the very right. If yours shows "Reduce the volume of other sounds by 80%", setting this to "Do Nothing" will correct your issue, as it did for me (this was irritating me just as much as it did you).
