I'm reassembling my AV system after remodeling the room and I can't seem to get any Youtube videos to deliver anything but PCM stereo from my Premiere Elite to my AV receiver. I seem to recall being able to do this in the past. Netflix and cable channels pass through Dolby Digital just fine. My setup is Tivo Premire Elite connected via HDMI to Yamaha Aventage RX-A800 connected to a Samsung UN55D7000 TV via HDMI. Is this a known limitation or do I need to keep on playing with my setup configuration?
