Ota hdtv audio signal

Anyone able 2 receive 5.1 with ota broadcasts? My receivers multi decoder doesnt light up so i assume its 2.0...
Yes, it depends on the program being broadcast. I get Dolby Digital 5.1 with most prime time shows.
Sure, almost all are now in 5.1.
Do u need hdmi 2 get it?
No, I am using regular digital (optical or coaxial)cable.
Something is either not functioning or set wrong on your set up.
