I have a Windows 7 SP1 System on an ASRock Z68 Extreme3 Gen3 Motherboard. Whenever I output any sound I get a clicking, echo over the output.

I output sound through a cheap pair of logitech speakers plugged into the audio-out on the back of the motherboard, or a pair of skullcandy "Agent" headphones plugged into the front headphones port on my case. I get the same echoing sound through either device.

My system also dualboots into a Kubuntu 13.10 OS. I have no issues whatsoever on the linux OS with the sound from either output device.

To attempt to fix this issue I have done the following, to no avail:

  • updated the Realtek drivers from the default version for my motherboard to the latest version from the Realtek website. The echo still happens.

  • I found a (used) usb soundBlaster "X-Fi Pro! Go" USB soundcard. Plugging this device in, and installing the latest drivers for it, also yields the very same echo

  • I dont have any physical microphones, nor anything plugged into the microphone jacks, but I did mute the microphone lines in the volume mixer

  • I disabled all audio effects on the Realtek and Creative control panels

I feel it has something to do with windows itself, since I get the same echo through two different soundcard devices, but not in another OS. A windows reinstall did not help (I had to do a reinstall for another unrelated issue).

Can anyone point me in the right direction for something else to try?
