Yamaha HTR 3066 - No dialogue from Center speaker

[dre@ms]

Guys, I have a Yamaha HTR 3066 and recently connected it with my Samsung Smart TV. When playing any 5.1 video from either Prime/ Netflix there is no dialogue heard from Center speaker. But if the dialogue comes from either side (due to surround) the dialogues are heard through the Front speakers.
Note: When the source is changed to Stereo, dialogues are heard.

Below is the connection.
Yamaha HDMI OUT > Smart TV HDMI3 (Arc) IN
In Yamaha, AV1 is selected.

Troubleshooting done so far,

1. Changed Levels from -10 to +10, no change
2. Changed surround to Straight, no change
3. Changed HDMI cables, no change
4. Changed Distance to near, no change

Kindy help.

There must be some setting in TV to send 5.1 audio. You can check info in Yamaha if it's getting stereo or 5.1 signal.

Yeah.. that helped. Changed the sound output from PCM to DD and it is now better. Will tune Yamaha to get optimum sound.
