I have a weird issue on my Windows 7 32 bit. Suddenly my volume decreases automatically to 0. I've made a video about this: http://youtu.be/weud4zvlry8

I've searched the internet before I asked this question here. These are the things people suggested:

  • Install latest audio drivers.
  • Unplug any USB-devices.
  • Disable the option to decrease volume when communication activities are detected.

None of these helped. Sometimes a reboot helps, sometimes not. I didn't have this issue for a week, now it's back again.

Edit: Now I noticed that even hibernate can solve the issue (temporary).

Is there any of you experts that have a clue about what could cause this problem and how to solve it?

    Do you have media buttons on your keyboard?

  • No I don't, just a basic Logitech USB keyboard.

  • I aint expert, but I have had this problem too, i think it was because of my microphone + wrong sound settings (to record system sounds you need to twiddle with sound settings a lot). so check your sound input/output settings (cant remember where to open it anymore, sorry), and see if they are ok.

  • @EsTeGe, can you check your bandwidth usage when you arent dowloading anything? i had a virus on my windows XP which mysteriously switched my sounds off, it was using 20% of cpu all times and downloading random youtube videos online all the time. maybe its the same virus but slightly different behaviour on win7.

  • @Rookie, I did a complete scan, and there was no virus found at all. I already have sound again without doing anything, but it will come back for sure just like it always does after a while.

Disable the bluetooth connection with your mobile phone.

This fixed it for me; in my case the problem occurred when turning my mobile phone on while windows was still running.

  • Unfortunately, there's no Bluetooth running at the moment.

  • Any other connection to a mobile phone? At least mine behaves just like when connected via bluetooth when connecting it via USB. May 17, 2012 at 10:06
  • I disabled all the Bluetooth services and it's still decreasing :(
