Ok, before I start, I am 100% sure this is not the speaker's problem. My older polk center speaker started giving out crackling noises during loud scenes (not necessarily load volumes if that makes sense). I was stupid and automatically assumed it was my center speaker's fault so I bought a pold csi a4 and replaced my old speaker thinking problem was solved. But the problem still persists and the crackling is still there.
What the heck is going on? I doubt this could be it, but a few months ago I started using an HDMI switch, but not sure how that could cause this. Any recomendations?
My reciever is a yamaha v663 and it was set up, for the most part, using the auto set up mic that comes with the receiver.
