No surround sound coming out from tv on internet
I have a panasonic tx-p55vt50b connected to my yamaha amp rx 1067 with a hdmi lead. The tv is a new purchase and I have set up a wireless connection to enable me to enjoy the various internet features the tv offers. No problem in accessing the various apps, but I'm receiving no sound via my amp. If I disable the amp, then I do hear sound via my tv speakers. I'm guessing I need an additional cable!
What I dont understand though is my ps3 is connected to the same amp via hdmi and when I access the internet via the ps3, I hear sound via my amp.
Can anyone provide me with some guidance please.
