If you are trying to pass the HDMI video/audio through the AVR when it is in Standby mode, simply set HDMI Control to ON and set the Standby Source to whatever HDMI input you want to pass through. If on the other hand you want to pass the video/audio through while the AVR is ON, then set the HDMI Audio Out setting to TV.
I'm screwed huh? what about optical out? isn't optical out on a device on all the time, so long as it is enabled? then couldn't the HK1710 function for sound only leaving my other devices hooked to the TV with audio as they would be sans surround sound, thus allowing me to turn the HK1710 off and on at my will?
I'm having just one heck of time with this and usually electronics and computers are my forte. Okay so 5.1 can work but, as it is now even with the cable box set to matrix i don't get sound from the rear speakers watching TV that is supposedly broadcasting in 5.1 grant it i'm hooked up via HDMI since the optical cables have not arrived yet.
