New firmware for LG C9 is out 5.00.03.

could anyone please kindly check if it can output DD 5.1 from Apple TV/switch etc to the Arc? I returned my Arc, so can’t sadly check it:(

 

thank you!

It’s not available on the website, but if you go to your settings > General > about this tv and click Check update it should see it.

I would love to know if this fixes the issue. Been holding on upgrading my tv ever since I got the arc.

For future reference: did you change any settings in Kodi to change the transcoding of DTS from DD to PCM/LPCM?

Hi,

here I describe my settings for the LG C9, the Nvidia Shield TV with Kodi and the Sonos Arc.

I have a Sonos Arc, a Sonos Sub Gen. 2 and two Symfonisk Lamps.

 

Firmware versions

  • Nvidia Shield AndroidTV: 8.2.1
  • LG OLED C9: 05.00.03
  • Sonos Arc: 12.2.1
  • Kodi 18.9

Settings LG OLED C9

All Settings - Sound - Sound Out- HDMI ARC:

  • Digital Sound Out: Pass Through
  • eARC: On

Settings Nvidia Shield TV Android

Settings - Device Preferences - Display & Sound - Advanced sound settings:

  • Dolby audio processing: enabled
  • Select formats: Auto

Settings Kodi

System Settings: Expert

Dolby movies (Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos) work with both of the follwoing described variants:

a) With the following settings your DTS movies get transcoded to Dolby Digital:

System Settings: Audio:

  • Number of channels: 2.0
  • Allow passthrough: enabled
    * Dolby Digital (AC3) capable receiver: enabled
  • Enable Dolby Digital (AC3) Transcoding: enabled
  • Dolby Digital Plus (E-AC3) capable receiver: enabled
  • DTS capable receiver: disabled
  • TrueHD capable receiver: enabled
  • DTS-HD capable receiver: enabled

You have to configure “Number of channels: 2.0” regardless of your setup. This is a Kodi workaround to get the transcoding option. You don’t see this option if you configure something else. 5.1 works this way.

b) With the following settings you get LPCM for your DTS movies:

System Settings: Audio:

  • Number of channels: 5.1
  • Allow passthrough: enabled
  • Enable Dolby Digital (AC3) Transcoding: enabled
  • Dolby Digital Plus (E-AC3) capable receiver: enabled
  • DTS capable receiver: disabled
  • TrueHD capable receiver: enabled
  • DTS-HD capable receiver: enabled

Hope this helps you to get this working.

 

Best regards Hoppel

Hi all, I’m having an issue that I haven’t seen discussed in this thread. Basically my C9 always defaults to internal speakers & Optical audio every time I switch on or change source. It’s really annoying because I have to manually go into the C9’s settings and choose ARC. Every time.

 

I had a similar issue when I first got my CX. Found the fix was easy... I had an optical cable plugged into the CX that I wasn’t actually needed/used. Unplugged it, then all was fine after that. Seems like the CX can detect an optical cable is plugged in and will then default to it (even though the other end of my optical wasn’t connected to anything). I know it’s 7 months since you wrote that, but if you still living with it hopefully that solves it for you.

Morning, just after some advice and didn’t want to create a new thread. Apologies if this is the wrong place.

I have just purchased an LG CX, 

when using the integrated apps the Sonos app is reporting Dolby Atmos (DD+) -  It is my understanding this is lossy?

When using Apple TV 4K apps the Sonos reports Dolby Atmos - Is this total lossless Atmos and should be the preferred choice?

 

Thanks
