TV's aren't built to do that. They aren't supposed to daisy chain connections like that.
The optical output on the tv is for getting 5.1 surround from your local HD channels, using the internal tuner, while using an antenna. That's all.
Some tvs will pass audio that way, but they down mix it to 2.0, to send to the receiver. Then, the best you can get is Dolby Pro Logic II (simulated surround).
What model Yamaha do you have? What model BD player do you have?
You can always get something like this:

Again, model numbers will help.

Ok, since the BD player doesn't have 5.1 multi-channel analog outputs, you're not going to get the HD audio from BD movies.
Digital cable boxes usually have a digital coax output. It is an RCA type of connection, usually color coded black or orange. It may even say coax over it. Your receiver has one digital coax input. If the cable box does have the coax output, you can use that for cable, and the two optical for the Xbox and BD player. Then you won't have to buy the optical switch. If the box doesn't have a coax output, you will need the optical switch.
Your receiver has 5.1 multi-channel analog inputs. If you get a BD player with those outputs, you can listen to the HD audio from BD movies, and get rid of that optical connection, and not need the switch. A BD player is more expensive than the switch, but you'll get the HD audio, which isn't possible over optical. Just some more things to think about...........
Good luck!

With an optical connection, or digital coax, you get regular Dolby Digital and DTS 5.1/6.1, which is good. It's just not as good as the HD audio formats (Dolby TrueHD and dtsHD Master Audio). With HD audio, you can get up to 7.1 discreet channels of surround (on several BD movies), which isn't possible from regular DD or DTS. Regular DD and DTS are "lossy" (compressed) formats. Dolby TrueHD and dtsHD MA are "lossless" (uncompressed) formats. Uncompressed audio is better than compressed audio..........
Optical and digital coax is much better than a stereo analog connection. They may even be better than 5.1 multi-channel analog connections, when watching a regular dvd. But they aren't even close to being better than the 7.1 multi-channel analog connections, when watching a BD movie.
If you have the digital coax output on the cable box, you won't need the optical switch. Otherwise, you will...........
