I got a new sound bar, a Yamaha YHT -S401 and have an audio question if you're interested. 1) The Yamaha YHT -S401 has a receiver with 4 HDMI-IN, and 1 HDMI-out with "ARC" support. 1 digital optical audio port. 2) FiOS cable box. 3) Toshiba HDTV with 4 HDMI ports but doesn't support "ARC." 1 digital optical audio port. 4) The Sony GS7. Current set-up: GS7 to FiOS box by HDMI. GS7 to ToshibaTV by HDMI. YHT -S401 sound bar to GS7 by digital optical audio cable. .................................. GoogleTV settings; "Audio Output (HDMI)" = "PCM" "Audio Output (Optical)" = Checked box "Audio Pass-through" = "Off" The sound with this set-up and settings is pretty good, and the receiver display shows either "PCM-ProLogic 2" or "DD Digital" depending on the content, but the "sound separation" quality doesn't seem to be as expected, even with no surround rear speakers, and the currently used: sound bar "left," "right" and "center" speakers, plus the separate sub woofer. I'd like to try a set-up with everything connected separately to the receiver by HDMI, but not sure if this is possible (or optimal) without the ToshibaTV "ARC" support. Any suggestions welcome, thanks.
