After doing some research for a friend's new Sony 7.1 receiver with HDMI inputs, I find that a separate coax/optical connection is necessary for the receiver to process audio from his "upconverting" DVD player. He's quite perplexed because as he understand it, HDMI carries not only high quality video but also digital multichannel audio as well. This is certainly not a deal breaker, but what has happened to the HDMI promise of "one wire does it all" hype?
Is this true for all brands of HDMI supported receivers/pre-pros?
The next question is whether this is true of all new blue laser format players? Are multi-patch cord audio connections (a la SACD/DVD-Audio) going to be necessary in order to hear the hi-res Dolby TrueHD or DTS-HD bitsreams in receivers of the future?
Thanks, and apologies if these questions have been covered on another thread here.
