Loudness/speech enhancement/night mode

Hi,
Just got myself an ARC and a Sub Mini.
When toggling the Loudness/speech enhancement/night mode on/off, nothing’s happening.
Do I need eARC to enjoy this feature?

I do have HDMI arc, but sonos could not find it, so I had to use the optical cable.
That’s okay, but just wondering if it has something to do with the HDMI.
Having said that, the loudness didn’t work in the store when they were demostrating it for me.
And that was through eARC.
Any tips?:)
Ken

Perhaps try playing Dolby Digital 5.1 surround audio and then toggling the speech enhancement/night sound buttons on/off as that type of sound input usually benefits with these two buttons. I find them really noticeable at night time when trying to not disturb neighbours and for some shows with poor front centre channel dialogue - Some examples of surround sound audio to maybe try (randomly chosen) are…

  • Jack Ryan Series 4 - Amazon Prime
  • Mulan - Disney+
  • 6 Underground - Netflix

I should just add the type of wired connection between the TV and soundbar is not relevant here.

    Thanks for your reply, Ken.

    I don’t have Amazon or Disney, but I found 6 Underground on Netflix.
    However it only popped up as Stereo PCM on the Sonos app.
    So I had to go back in to my TV settings and choose HDMI for sound out, instead of optical.
    Then it shows Doly 5.1. However there is a lag, so the sound is quite a lot behind the film.
    This is the reason I had to choose the optical out yesterday.
    Anyway, the speech enhancement/night mode still doesn’t work...even though it’s out of sync🤔

    Which TV is it - make/model? Where is the Netflix app located, is it built into the TV, or on a device connected to the TV? If it’s on a separate device, then set the audio to ‘pass-through’ the TV ports, rather than being processed by the TV itself.

    Yeah sorry, forgot to provide that info:)
    It’s LG 55ub830v-zg
    It’s kinda old TV, but it does say HDMI arc on the port and the TV has the latest update.
    However the Sonos app never found the HDMI, so I had to use the optical.
    I watch Netflix through Apple TV 4K.
    I tested HBO and a few other apps. They all lag a bit...but not as much as Netflix.
    I can’t find a way to “pass through” the audio on the Apple TV. “TV Speakers” is the only choice that pops up as alternatives.

    It’s not an Apple TV setting - it will be in the ‘sound out’ settings on your LG TV - it maybe set to Auto. Change the HDMI-ARC port (when in use) to pass-through. That’s if the TV has that option.

    Also with some older LG TV’s there’s an option to bring the audio into sync with the video on screen. You need to perhaps consult the user manual for the TV. 

    I assume on your Apple TV you have switched off Dolby MAT Multichannel LPCM audio output too and just using Dolby Digital 5.1? (Audio Format/Change Format = ‘ON’)

    I see.
    The only active choices I have on the TV is “AV sync. adjust”, which I have tried both on and off.

    On the apple TV I can’t find any alternatives for Dolby🤔

    Probably because my TV is not 4K.

    Many of the screenshots you’re posting are not entirely relevant. If you enable the A/V sync on the TV, you still then have to go into that LG feature and adjust the lip-sync control to get it into sync (it’s a manual process IIRC). Also you still ideally need to consult your LG TV user-manual for the digital sound out pass-through setting, because if it is available, you can probably leave the A/V sync setting disabled.

    Your Apple TV audio format is set to ‘Auto’, but I would switch that to ‘ON’  and select DD 5.1 as your TV has no eARC port, That’s really just so that its showing the correct DD 5.1 audio output.

    No, that’s not relevant here, DD 5.1 will work fine with a HD 1080p TV.

    Yeah, I put the Apple TV on on Dolby 5.1😊
    But now I don’t have sound at all. It seems like the arc has lost connection with the tv somehow.
    I’ve tried everything for 15 minutes now. 
    Trying to figure how to do the setup from scratch, but can’t find it in the app. 
    I need some air now, so I don’t throw the whole bar out the window😂
