I cannot find the codes in the Logitech database listing for this LCD TV for designating "TV Speakers" or "Audio System" under Audio in Home Directory/X Cross Media Bar or under Options. Does anyone know where these can be obtained?

I hook up my TiVo HD box via Component directly to the Sony and all my other components (DVD players, etc.) via HDMI to my AV Receiver and HDMI Out to the set. As the first option utilizes the TV's speakers and the second my Klipsch 5.1 HT system, I would like to set up the Harmony 880 to include the switch from one state to the other as an additional command sequence on Power On or device switching.

Can anyone help me here? I've just posted this on the Logitech Forums and wanted to "cast my info net" wider.
