Is there an adapter for an HDMI cable that would split off the audio so I could go directly to my receiver/surround system? I'm running the HDMI from my PC to my TV, but have no pass thru sound on the TV to go to the receiver. It would be great if the adapter split off the audio but also continued with the audio to the TV. So it would be a full HDMI connection to the TV, but the adapter would allow the audio to go to the receiver. Then I could use the surround sound whenever I choose or the TV sound. Make sense, or am I dreaming ?
