I have a Pioneer 1021-K receiver. Everything is routed through it via HDMI and sent into the VT50 via HDMI. I just bought a pair of wireless headphones that I want to use while my wife is sleeping, so I'm trying to run the optical out on the VT50 into the headphone base. However, in trying to do this, I've noticed that there is no audio coming into my TV from the receiver.
I started fiddling around with things and I've noticed that I'm unable to go into the audio settings on the VT50 at all. All the options are greyed out including the option to reset to defaults. Advanced and SAP options are available, but when I go into advanced I can only select whether it's HDMI or component for each input. Things like turning the TV speakers on and off are also greyed out. When I try to turn up the volume on the TV itself using the TV remote, it actually turns up the volume on the receiver instead.
What setting have I adjusted to put the TV in this state? And further, is this setup I'm trying to accomplish even possible? Thanks!
