That's one way of *getting around the problem*, but that doesn't answer my question as to why this tuner can't/ won't send a variable audio signal to my TV via the HDMI. Personally, I leave my receiver/processor volume static and vary the digital audio signal by the tuner/optical toslink as the Rogers remote default is set to the tuner this is simpler for multiple family members who don't want to fiddle around with various items to function, but with this scenario the Cisco tuner won't let me do that.
I wish i had an anser. I can test mine tonight to see if i can get it on mine.. While the box is possible that it can do it, with the custom firmware, etc.. it may be disabled? Not sure.. I will post back if i get any findings.
