If there is an input/output, you probably could since the HDMI carries both audio/video

With all due respect, PoohBear's answer is incomplete.

I have a Sony STRDG 810 receiver, and it does exactly that: "picks off" the audio and sends the picture along to the TV.  

However, some receivers (and I can't find enough information online to tell you) only do HDMI "passthrough", which means they just act as a switch for your TV, and have to receive an audio signal in some other way.

If the Yamaha has "passthrough", it won't play the audio; if it is a true HDMI receiver, it will.

No, Yamaha 463 is a HDMI passthrough. It means if you connect component video from DVD to Yamaha 463, you need one more component video output from Yamaha 463 to TV to get picture. HDMI switching or repeater receiver means you only need an HDMI output from receiver to TV, no matter what kind of video cable ( composite , S video , component ...) connected to this receiver. It also carry audio via HDMI.

No, no receiver can decode the HDMI signal, pick off the audio portion, and pass the video portion through to your TV.   The receiver can only pass the entire signal - audio and all - to your TV.

Which makes it rather annoying since HDMI was designed to carry both the digital audio and video signals together, while reducing the number of cables running between your devices.

Unfortunately, folks at the Movie Picture Association of America (the MPAA) various studios and other content creators pushed to have all sorts of DRM and encryption put on top of the HDMI standard - which is why no receiver can do what was originally the whole point of having HDMI in the first place.

As a result, HDMI is basically just a new fancy video cable with all sorts of glitches due to the complexities of the poorly implemented security systems to allay the studios' paranoia about people actually being able to watch (much less enjoy) the content they've paid for in HD.

The upshot of all this is that you still need to run a separate digital coax or optical audio cable from your device (e.g. blu-ray player) to your receiver in addition to the HDMI cable.  This only makes sense if you plan on using your receiver as a centralized switch.

Some newer TVs appear to have the ability to pass the digital audio signal from an incoming HDMI connect back out to a optical audio cable which you can then connect to your receiver for surround sound.  However, this feature only seems to be on TVs from the past 6 months or so.  Check your manual carefully to see if your TV has this feature or not.

If your TV has this, then you can just run the optical audio cable from your TV to the receiver.  To listen in surround sound, turn off your TV's speakers.  I don't mean turn the volume down - go into the TV's setup menu under Sound and turn the speakers off so the TV will use the optical audio output instead.
