I have SkyHD and an Onkyo 818 Reciever.

I have Sky -> Onkyo -> TV plus I have Xbox360/Igloo/PS3/AppleTV/RaspberryPI etc all plugged into the Onkyo as well with different inputs.

What I find is every time I turn on the TV/Onkyo in the morning I get no sound (from Sky) until I change channels on the Sky Box. Video works fine . Just no sound (not a HDCP issue)

All other devices work fine regarding sound. its just the SKyHD Box.

Anyone else have similar/same problem? It feels like the Sky Box forgets to send audio after the Onkyo goes into Standby.
 
before you ask.. yes I've changed the HDMI Cable from Sky a number of times. The Onkyo has the latest firmware. I've changed SKy HDMI output settings a number of times and tried all the Onkyo Input settings as well.

Yes I can plug the Sky Direct into the TV (and no problems occur) but then the AMP doesn't get used for sound (Unless I use Optical output).
