I recently put a new GForce4 MX SE (PCI, from xFx) in my friend's PC.
Now he claims that during audio playback, he often hears a little "scratch"...
I went to hear this phenomenon and I found out that this was only the case when using streaming audio from apps like Windows Media Player, etc. (MP3, WAV, ... directly from hard disk)
It was not the case when using the ordinary Windows Sound Recorder, because this loads the whole sound file.
The PC never did this before.
Any suggestions?
