I have a new HDTV, a Yamaha receiver, HD cable TV/DVD box and an Xbox 360 with optical out. My Xbox and cable box both have optical audio outputs. My receiver has ONE optical input. It also has a single digial coax input and that's about it.... The Xbox 360 audio output (RCA stereo) and Cable TV audio (HDMI) are going through the TV, and the TV optical out is connected to my older (circa 2003) Yamaha receiver. Obviously, this isn't ideal since I want to maximize sound quality from both audio/video sources. I understand the "best" solution would simply have the outputs going from both Xbox and the cable box to the receiver, but I'm unsure whether I want to try to use an optical-to-digital coax converter box which I saw online, or try to use an optical splitter (which I'm afraid would not work when both the cable box and Xbox are on at the same time. Another thing I find VERY annoying is having to switch both the audio and video sources separately. If I want to go from watching cable TV to watching a DVD, I have to click "TV input" to select the video and then click "Aux Input" repeatedly on my remote to select the corresponding audio. It would be MUCH easier if there were a way to simply click "Input" on the TV and have that also change the audio input on my receiver. So far I haven't found a way to do this, though... Thanks for any ideas on how to easily maximize this while making switching between audio/video sources less cumbersome. I guess if I had to choose I'd opt for the best audio quality I can get, but having both pass through the TV is more convenient when switching sources and not having to futz with the inputs on the receiver.
