So I recently gave my parents my surround sound system (Samsung HT-E3550). I set it up the same way I did on my TV at home which is also a Sony TV. Their TV picked up the system and comes up with a prompt "audio system active" although no sound is coming through the system. As said earlier, it was set up the exact same as I did on my TV. Same prompt came up. But no sound. I have also plugged in my optical cable to see if that was the issue. Did not make any difference though.
Any suggestions?
Other Info:
Audio system is set to D-IN
TV has freeview built in, which is what I am trying to get sound from.
Tried on analog, that didn't make a difference.
