Re: high pitched noise
go to your sound settings in your control panel and it has steps for you to
check to see why your speakers are not working properly.Make sure that you have the drivers
installed. You might want to re-install your drivers. Look in your device manager
for this.If your device manager has a
question mark by your sound drivers then the drivers are not installed.I hope that I hope that I helped you Solve

Sometimes High pitching its just that, static on the area, like if you are near a microwave, or near other electronic equipments, but, if the skreetching sound keep going or even if you do nothing it could be a line inside the sound card, or you need to clean the volume botton with special electrical cleaner. other that these, its contacts, or bad cap for the volume board inside.
check your wires if they are too near some big power wires and move them away from these high powered wires or check your grounds and make sure its a good ground by scrapping the connection until bare metal. Also its a possibility rca's or wires are getting pinched or not fully connected.
if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and Crutchfield.com. First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.
