How To Set Dolby Digital Plus?

Hi, I'm new to Home Theater world so I'm sorry if my question sounds silly or stupid. I have Samsung 40MU6100 TV and Samsung HT-J5100K Home Theater, and afaik both support Dolby Digital Plus. I've spent hours trying to figure out if DD+ is configured properly but I haven't found an exact answer. I have updated both unit firmware to the latest version, and Home Theater unit is connected to TV through HDMI ARC and optical cable.



From the TV sound settings (Expert Settings), HDMI Input Audio Format gives me 2 options (PCM and Bitstream), while Digital Output Audio Format gives 5 options (PCM, DD, DD+, DTS and DTS Neo 2:5), but except for PCM and Neo, other options are greyed out. I'm a little bit confused because from what I read on Internet, optical / digital audio doesn't support DD+, and HDMI input supposedly supports that. Is that true? please cmiiw for this one.


From Home Theater unit sound settings, there's a couple options (including Speaker Selection, Audio Return Channel and Digital Output). First, I selected Audio Return Channel to "On". On the other hand, with Speaker Selection selected to "Home theater speakers", the Digital Output setting is greyed out, I have to change the Speaker Selection to "TV Speaker" so I can set it to PCM or 3 Bitstream options (Unprocessed / Re-encoded DTS / Re-encoded Dolby D), Hence my 2nd question, which should I choose?



I've watched some Dolby 5.1 test video from Youtube, and from what I can hear, all speakers function normally. When testing center speaker, both surround speakers also has audio. With front right speaker tested, I can hear audio coming out from right surround (but not from left surround), and pretty much the same for the left speakers. This maybe nothing but while watching some movies from cable TV channels that supports 5.1 Dolby, I can't hear sound from surround speakers, I have to change the EQ to Cinema, Game, or S-Mastered to get them working.



Am I missing something? Please help and TIA!

Many smart TV's offer the ability to send Dolby Digital + audio as a bit-stream via HDMI ARC.

Needless to say, your TV's HDMI audio output options must be set to 'auto' (not forced to Dolby Digital +) and any content you're viewing must contain an actual Dolby Digital + audio stream.

Do you have any content that offers a Dolby Digital + audio stream?


Cheers
