I have the Yamaha HTR-3066 receiver in my home theater setup. All the inputs are via HDMI cables. When I plug wireless headphones into the headphone jack, the speakers do not play (as they are designed). I would like the option to wear "supplemental" headphones (to aid in hearing better) without having to "blast" everybody out of the house with the speakers being too loud. Is there a way to add a bluetooth transmitter to the receiver? I've tried plugging the BT receiver into all the AV output jacks, but because the HDMI outputs are actually what I'm "tuned into", there is no output from the AV jacks. In reading the manual, it looks like there is a a way to select the AV jacks as output, but I can't get that to work. Any help here?
