hello everyone.

I would like to ask you for help.

I use kodi streaming services and all my movies play in audio track: stereo PCM.

I own a sonos Beam gen 2 + 2x ikea symphonisks.

The last movie I saw now, John Wick 4, had audio features: codec atcs a/52b (ac-3, e ac-3); 6 channels; layout 5.1 (side).

Could I ask You for advice on how to get my movies to play at least in 5.1 format (when the side speakers are connected)?

Thank you very much

It’s probably down to your TV’s audio settings. Which tv do you have?

I assume the Kodi App is not available from the LG store, so is it installed on another device connected to the TV - have you set that connected device to play Dolby Digital (Plus) 5.1 audio? and set the TV to ‘Bitstream’ and ‘Pass through’ on its ports?

Thank You. Its correct. Another device - Xiaomi Mi TV Box S EU

 

Bitstream’ and ‘Pass through’?

No. I didn't do anything like that. could you please advise me how to do this?

Goto the C9 TV ‘Settings/Sound/Additional Settings’ and set the port in use by the Xiaomi Mi TV Box S EU to Bitstream.

Goto ‘Settings/Sound/Sound Out and set the HDMI-ARC connection ‘Digital Sound Out’ to ‘Pass-Through’.

If the above doesn’t solve it, then it’s likely the sound-out settings on the Xiaomi Mi TV Box - which I don’t personally know too much about …and you will need to consult it’s ‘User Manual’ for its sound-out settings, or perhaps ask on their support forum.

      Good day.

      So I bring the promised information. I already had your recommendation set up from before.

      I tried a Netflix movie on the Xiaomi device and it sounded similar to the Netflix app on the LG TV.

      So it looks like the problem will be with the KODI app.

      *I found in the TV another settings: DTV sound settings (MPEG, Dolby digital, Dolby digital plus, HE-AAC, Auto). should I choose Auto?

      I have another question.

      Do you have experience with the device: NVIDIA SHIELD TV PRO (2019)?

      Thank you

      Yes ‘Auto’ should be absolutely fine, but you could also try DD+ or even Dolby Digital, just to see if it makes any difference.

      I have experience with Nvidia Shield TV - the bar-shaped version of their product,  but not the Pro version.

      I suspect it’s the Kodi version of the App too, but are there any audio-out settings you can perhaps change in that App?

      I was curious and made a small attempt.

      I went through the older movies I watched through Kodi and came up with the following.

      Kodec AC3 5.1 - movies boiling point, Marcel The shell, it works

      X

      Codec AAC 5.1, DD+ 5.1 (side) - movie John Wick 4 - does not work, switches to stereo PCM.

      Do you have any insight on this?

       

      Next, I found Kodi's internal audio settings. i enabled all available formats including DD+ but it didn't work for John Wick 4...

      And does the Dolby digital plus codec work on your nVidia Shield device?
