Hi
Setup:
Samsung LED TV
PS3
Digibox (for television)
PS3 and Digibox connected with HDMI to the LED TV
Optical cable from the soundbar to the TV.
Optical cable shows red light.
No sound, then I updated the firmwire, and tried to connect the subwoofer with the soundbar, but the WiFi led is searching and I'm keeping the MUTE to the soundbar but it wouldn't connect.
At first the subwoofer was connected but also no sound then.
At the TV I set up "external" at the sound options.
