i hooked up my pc to tv via rgb, video fine. i used a male/male stereo jack from audio out pc to stereo jack audio in tv, sounds good at low volume but when the volume is up it sounds like a buzz or humm. any suggestions ?
If Robert's suggestion didn't work then I suspect the PC volume to be way too low. Try setting it just short of half way and turning down the level on the TV.
In other words the TV's (very poor) audio amplifier is doing the best it can with a very low input. Increasing the gain of the input signal should improve the output.
