Hey everyone! A couple days ago, I bought a soundbar for my grandparents. The soundbar is a Toshiba TY-SBX130B, connected to the TV by an Optical Audio Cable, and works great and their Blu-ray Player plays audio through the soundbar no problem, but when their TV (Samsung LN46B500P3F) is on regular Over The Air Antenna, no sound comes through the soundbar, no matter what channel it is, and I have to go back to the TV's internal speakers in the settings. The soundbar manual says to switch the audio mode of the TV to PCM, which I know to be true, as I hooked the soundbar up to my TV and had to change the audio type to PCM. However, no matter where I look in the TV's Settings, there isn't an option to change the audio type to PCM.
