This is what I do as I haven't been quite ready to upgrade my receiver. My TV has plenty of HDMI inputs so I really don't need the receiver to do any HDMI switching.
Possible work around if you are willing to accept non-HD audio but happy with Dolby and DTS (assuming your receiver handles them)
Blue ray HDMI to TV
From TV - OPTICAL out to receiver.
What you are doing is letting your TV get all the signal then pass audio out to your receiver. What is required is that both your TV and receiver should handle optical out (Tosslink as example). Many TVs have stereo analogue out but Optical out should handle surround sound.
Assuming the above is possible - when you play Blu Ray movies, go to the set up and pick DTS or Dolby (which ever is on the disc) as opposed to the higher end audio (DTS-MASTER as example).
The TV ideally should have a setting that chooses whether the TV's own speakers are working or if it should pass the audio out via the optical connection.
Please let me know how it goes as I admit I should have offered this possibility in my original post response.
