Can people please run the following test on their boxes and report what they are using and what they hear:
box: Echostar
cable: hdmi
avr: onkyo
I hear a hum during the quiet parts or silence of a programme, BUT IF I PAUSE THEN THE HUM DISAPPEARS.
This is most noticeable through an amp rather than the TV's own speakers. In fact you cannot really notice it via the TV's speakers or via the amp when the amp is soft.
It is apparent on both Dolby and aac/mp3 sound formats from the box.
As the hum disappears when you pause a recording or live TV suggests the speakers are correctly wired and noise is not being introduced there.

) - I don't know if any still do. It's possible/probably that your set top box is sending digital silence when paused.
