Default 3.0 Soundbar

Hello,

I'm using a 3.0 Vizio Soundbar with my tv. It's connected via hdmi directly to the tv (no receiver) and i was wondering:

1. If I am watching a 5.1 audio mix, the right, left and center channels emit sound, but what about the sound for the surrounds in the mix? Is it folded into the left and right channels or is it just lost? What about a 7.1 mix?

2. Stereo audio mix just has a silent center channel right?

3. Mono just would have all 3 channels emitting the same sound?

4. If it's an Atmos mix, how would the soundbar handle this? My soundbar doesn't have atmos, but on the blu-ray menu i can switch to it.

Thanks.

1. Folded down. Ditto 7.1. Without knowing quite what bar it is and what formats it can decode, you might only get stereo fold-downs for some audio formats like DTS. Same goes for the TV, if it doesn't do DTS it'll only be feeding the bar with 2.0 for DTS soundtracks.

2. Possibly, the bar might also have processing options to expand it to 3.0.

3. Depends. If the above is relevant, it'd probably channel it all to the centre speaker. It could also be dual mono (left and right).

4. It'll ignore the Atmos extension if if isn't compatible. Again, you won't lose any sounds, they'll just be within the 3.0 fold down.

So basically, while that's the gist of it and a lot goes across the board to all similar gear, some is dependant on exactly what your TV and bar can handle as not all do stuff like DTS, which is mad as it's the dominant Blu-ray audio format, but there you go.

Thank you so much for the info.

My TV lists
Audio Power (Watts)
2 Channel x 8W

Audio Passthrough
Dolby Digital Plus

Dolby Processing
Dolby Digital

It's a tcl 6 series 55P607 that I bought in 2017.

My sound bar is SB3630-E6S it lists:

DTS Studio Sound, DTS TruSurround, DTS TruVolume, Dolby Digital

So it looks like the bar supports dts, but my tv does not. I did find a post on another forum where a user discovered that the same tv I have would not pass dts:

"I connected my Blu Ray player directly to the TCL and then ran HDMI ARC from TCL to my Denon x3300. The TCL will not pass TrueHD, DTS-HD or Dolby Atmos from its built in HDMI ports thru ARC to the Denon. The best I got was DD+."

I've been planning on buying a sony ubp-x700 to replace this cruddy Magnavox player I've been using.

That Sony has 2 separate HDMI outs a combined audio/video out and a audio only out. I wonder if I could use the audio only out to send the audio from the player to the sound bar while sending the video from the audio/video out to my tv. Would let me take advantage of some better audio. I'll need to research that.

Again thank you for all the help. I'm a noob to this kind of thing.
