the sound is crappier than ever. I have this quality loss for a while but now is repulsive. Ive reinstall windows 7, reinstall relatek drivers, get ones specified by my motherboad manufacturer, tried the latest ones.... put power management at high performance...etc
my motherboard ASUS - Motherboards- ASUS P5GC-MX/1333
My RealTek sound (on one PC) also has "Sound Enhancements" which include reverb, echo, chorus, etc. If you have this diable all sound enhancements and see if that makes a difference.
I dont have enable any of those. On other windows 7 forum Ive got this more technically answer:
"When you say high pitched, I immediately think of 2 things, fan/motor bearings or capacitors "singing" as some do when going bad.
So to start, are you 100% sure the sound is coming out of the speakers? Have you tried another set of speakers? Since all the amplification circuits are typically integrated into the speakers (usually sub-woofer), you cannot assume they all work properly.
How much free disk space do you have? If limited, sound, being a low priority process, suffers.
Poor grounding and/or poor connections are classic causes of lousy fidelity so make sure all your speaker connections are securely connected - from the sound device and out to each speaker."
