I am using a desktop (no discrete sound card) with Windows 7 installed. The motherboard's audio is Realtek ALC850 7.1 channel AC'97 audio codec.
Normally, I either used a Altec Lansing (the "big speaker") or the apple's default iPhone earbud for listening anything from the PC. There is this weird thing that I pondered so I decided to ask.
There is a tiny short noise coming out of my earbud occasionally. The noise is noticeable, yet it is not to the point of annoying. The noises seem to occur on the following occasion:
1. randomly even when doing nothing.
2. when I scroll something. (for instance, scrolling a web page up and down will cause the noise)
3. when I highlight an item. (for instance, an icon on the desktop, a bookmark link on Firefox window)
4. during loading something.
I tried reduce the sound volume to 0, but the noise is still there. I tried increase the sound volume to maximum, the noise is also there, but the noise's volume remains the same; it doesn't get louder according to the volume setting. This implies this sound does not come from a usual sound output source. It's as if this is the sound from the computer processing or something else. Is there a way to eliminate this noise?
