Full Version: How to get Dolby Atmos to work

Hello all,

I’ve just bought an LG SL10YG sound bar. Before receiving it, I downloaded a bunch of Dolby Atmos demo videos but I can’t get them to work. The sound bar always receives audio in PCM format. Confused

My setup:
TV = 55POS9002 (Philips Android TV)
Kodi (Leia) setup on the TV itself
TV and sound bar connected through HDMI ARC

On Kodi, selected 7.1 audio, enabled audio pass-through and enabled all audio formats (Dolby Atmos and DTS-X weren’t there though).

On the TV audio config settings I tried different things like « multi-channel » or « Dolby Digital ». No matter what, the sound bar kept saying it was receiving a PCM signal.

I read old answers saying that HDMI ARC might not be able to send through DTS-X or Dolby Atmos data but will be able with an update.

Question : is it still impossible to get Dolby Atmos through HDMI ARC?

I also have an Nvidia Shield I disconnected when I’ve been able to install Kodi straight to my TV. Should I reconnect it and how? Perhaps with an HDMI splitter so I get one HDMI câble going to my TV and one to the Sound bar?

Thanks a lot for your help.
HDMI ARC does not have enough data capacity to support the transmission of Dolby Atmos content that is encoded using Dolby TrueHD.

Select 2.0 channels audio in settings for audio pass through HDMI. An HDMI splitter will introduce some handshaking problems. Dolby Atmos is a proprietary format and as such hardware manufactures pay royalties to Dolby for the privilege of incorporation into their hardware. I haven't heard of any magic sauce that fixes this. Audio quickstart guide (wiki)
