I do not use Amplitude, and should just delete it.

Buffer overload, hhhmmm most likely not since i heard it on two separate sound cards.

Maybe antivirus, will turn it off and see. But i kind of remember it when i did not ahve antivirus setup.

IRQ maybe will dig into that one.

It does not ahppen often or at the same place in a song. Sometimes i can play the song, and stop and go back and it will not do it.
