Sky Sports graphics interfering with sub woofer?
Hi, new to this my first post, always been able to find what I wanted without asking
Had to replace my old Pioneer VSX-2016AV amp (new furniture TV cab to small) with a Pioneer VSX-S500
Finally got it all working but occasionally I have been getting strange noises from the sub woofer, rumbling popping sound, didn't know what it was, but whilst I was watching the live football on Sky sports it was happening quite a lot, then I noticed it was corresponding with the on screen graphics, the replay graphic, the pop up scores at the bottom of the screen, the video window when they are advertising forthcoming events etc.
Each particular graphic has its own sound very similar to each other, but the same every time.
Sky 1T HD box
Samsung 46E8000 TV

Sony BDP460 Blu ray
Canton Cinema 5.1 Surround speakers including active subwoofer
Connections Sky direct to TV HDMI2, Sky to Amp Optical, Amp to Sub coax to low level input L, Amp to TV HDMI3 & Optical, BR to Amp HDMI
Thanks in advance
