I have had my Sony STR-DG910 hooked up in my home theater setup for about 6 months now. During that entire time, I have noticed a very annoying high pitched frequency coming through the center channel when there is dialogue. It gets even worse and much more noticeable when the video is of another screen (ie- a scene where a guy is watching a monitor or a computer screen). It is getting very annoying since I spent all this money on both this unit as well as the sony SA-FT3H speakers. If anyone could point me in the direction of fixing this annoyance, it would be greatly appreciated.
-ps- I am referring to my cable box, as well as ps3, both hooked up via HDMI
Thanks,
Huck
