I have the Pioneer VSX-1120, Panasonic DMP-BD85, and the Sennheiser HD558 headphone. I have a few questions on HD audio with headphones.
1. I have my blu-ray player set to bitstream the HD Audio and my Pioneer receiver can't process the hd audio when I use headphones, it downmixes the hd audio to stereo, thus I can't use the headphone surround option in my receiver. Should I setup my bluray player to decode the hd audio and send it as a pcm signal to my receiver in order for the headphone surround sound mode work with the HD audio?
2. If I set my blu-ray player to bitstream the HD audio and my receiver downmixes the HD audio to stereo while using headphones, will it be 2 channel HD audio?
3. When using headphones, what is the prefered method when listening to hd audio: HD audio downmixed to stereo (bluray player bitstreams HD audio), or use the headphone surround mode (blu-ray player sends audio as PCM)?
