How can I rule out the decoder? My amp has the latest firmware, and only does this on DSTV, all other sources are DEAD quiet.
It is still there using optical and HDMI - can also be heard when surround is off or on, its also there in-between changing channels.
If I'm on a channel - and the signal strength is 98% - I can still hear it.

Onkyo TX-NR807 - speakers are Polk audio Rti-A9s (not sure if they're relevant though).
