Why does my Sony computer mute itself when audio enhancements are turned on?

Jerome Gideon May 29, 2013

My laptop mutes itself and Windows Media Player is unable to open anything when I activate enhancements such as Virtual Surround or Loudness Eqiulization. I am using a Sony Vaio VPCEH28FN running Windows 7 Home Premium. The sounds are heard only if I switch off the enhancements.

    “Virtual Surround” simulates 5.1 surround sound with two speakers or “Loudness Equalization” improves volume for several applications such as media players

    1) right click on the volume icon and choose playback device
    2) choose your speaker and click configure
    3) also while speaker highlighted select property go to advanced try 24bit, 48000HZ (studio quality)

    -go to device manager, locate the audio driver
    -right click on it and choose uninstall (do not delete)
    -reboot windows should install the audio driver
    check if problem solved

      But wouldn't uninstalling, remove the advanced features and only keep the basic audio driver of Windows ? As he mentioned that already works, only the advanced features doesn't.

      uninstalling driver will not remove any features that are not related with the driver installer

      I saw your reply on the Microsoft Forum. I also faced a similar situation. I have a W7_64 system with a Logitech Headset with Microphone. When I had the enhancement enabled, I could hear peoples voice in Skype, but they could not hear me, even with a +30dB my voice sounded very faint and was hardly audible. After ticking off the enhancement, everything worked fine. I have no clue, why this should happen at all.
