My current audio receiver does not support HDMI. So, I currently have HDMI from the STB -> TV, and optical from STB -> Receiver.
The downside to this is I have to switch inputs on both the TV and the receiver when using a source other than the STB. I will soon have a new receiver that does have HDMI. My planned connections then are:
HDMI STB -> Receiver
HDMI Receiver -> TV
Does the HDMI signal coming out of the STB support the same digital audio signal that the optical outputs? Or is it 2-channel only? Some of the threads I have searched indicated it might only support 2 channels, but they were also a little older, so I wanted to ask.
