LG C9 and Sonos Arc

Hey all, my Arc was delivered this morning and I've had a chance to hook it up to my LG C9 directly via eARC and ran a few tests regarding Atmos and other features.

Built in apps:

Netflix - Reporting Dolby Atmos (DD+) for Atmos content.
Disney+ - Reporting Dolby Digital Plus 5.1 (though this is likely due to the current throttling taking place in the EU)
Amazon Prime - Reporting Dolby Atmos (DD+) for Atmos content.

Xbox One:

HDMI Audio set to Bitstream out and Bistream Format set to Dolby Atmos has no delay, finally! Displays Dolby Atmos in Sonos app.

PS4:

Like with the Xbox, there's no delay on Bitstream HDMI audio

NVidia Shield Pro:

Netflix - Reporting Dolby Atmos (DD+) for Atmos content.
Amazon Prime - Reporting Dolby Atmos (DD+) for Atmos content.
Disney+ - Reporting Dolby Digital Plus 5.1 (though this is likely due to the current throttling taking place in the EU). After connecting up to a US VPN it's reporting Dolby Atmos (DD+) for Atmos content.
PLEX - This is where it gets slightly annoying. Playing TrueHD content it reports Stereo 2.0. Setting Passthrough to HDMI reports Dolby Atmos (TrueHD). For DTS content you need to switch the Passthrough setting to Optical which in turn causes TrueHD to playback in Dolby Digital Plus 5.1.

Apple TV:

iTunes Content - Reports Dolby Atmos for Atmos content. Non Atmos content reports Stereo 2.0. With Change Format > On and New Format > Dolby Digital 5.1, I receive Dolby Digital 5.1 from non-Atmos iTunes content. I ran this test using Beetlejuice and Avengers Assemble.
Netflix - Reports Dolby Atmos for Atmos content.
Amazon Prime - Reports Dolby Atmos for Atmos content.
Disney+ - Reporting Stereo 2.0 for all content bizarrely. Setting audio output on the Apple TV to Dolby 5.1 allows all content to playback in 5.1 rather than stereo.

My C9 is running firmware 04.80.03 with the following settings:

Sound Out

HDMI ARC selected

Digital Sound Out set to Passthrough

eARC set to ON

Additional Settings

DTV Audio Setting set to Auto

HDMI Input Audio Format set to Bitstream.

If there's anything else I can test or any questions, let me know!

Mike010101,

DTV Audio is located at “Settings/Sound/Additional Settings"

That’s for Digital TV channels. As in your satellite channels, not your HDMI inputs.

I was just answering the question and pointing out where the TV setting is located on the C9. I don’t have satellite either and there’s only digital TV channels here in the U.K. There’s no analog channels? Anyhow this is the info displayed, concerning the ‘audio output’ if that helps at all.

Digital TV is DTV.

The point is that it has nothing to do with his problem or this thread to begin with. You’re welcome.

Mike010101 has only posted the one question in this thread and to quote his post... "Where is the 'DTV Audio Setting set to auto'?” …

I can’t help it being off topic, that’s something you may wish to address with him, but it’s clear to me that he was merely trying to perhaps check/copy the C9 settings that were working for Zophop.

I was just explaining where he could find that TV setting.

And I explained what it does. I don’t understand your problem here?
