I am getting a popping or clicking sound from my speakers every time the STR-DH820 receiver sound mode changes (from DD to LPCM or DTS, etc). What is the cause and anyway to minimize this? It is most noticeable when a DVD sound output changes from DD 2.0 to 5.1 etc. during future movie trailers or from cable box sound output changes from DD 2.0 to 5.1 when changing channels or commercials. All components are connected thru HDMI.
