I have recently bought a Panny ST60 and I was watching YouTube but couldn't get the sound to go through my 5.1 receiver (only came from the TV speakers), even with the cable in HDMI 2. Apparently you need to set Viera Link to "Home Theatre" for it to work but I can't access Viera Link to confirm as I keep getting the message "Feature not available" whenever I try to access the setting ?!? I'm using a TEAC AG-D200 receiver (basically an Onkyo TX-NR 515) and have it set as follows: - HDMI Ctrl (RIHD) = ON HDMI Through = AUTO. AV set-up is as follows: - AV Out --> TV AV In 1<-- Sky+ HD AV In 2 <-- BluRay AV In 3 <-- Raspberry Pi AV In 4 <-- XBOX FYI - All cables are HDMI 1.4a Any ideas at all ?
