Lip Sync issues - Sky Stream

[koopie]

Don't hold your breath on getting Sky to fix this any time soon. The issue began with Sky Q and ARC and has been carried over into Sky Stream. It's been an issue at least since 2016 when I got my first ARC tv.

Ok cheers. So just to confirm you think Passthrough is the better option than PCM stereo if I'm using a soundbar? 

[Veii]

I get it really bad on Animal Planet but not other channels. It has been doing it since I got Sky Stream on November 7 and is still doing it weeks later. I haven't noticed it on any other channels, not even other Discovery owned channels, it just seems to be the Animal Planet channel. I don't use Dolby Atmos or soundbars so it is set to Stereo and it gets restarted all the time when I unplug it to take it upstairs or downstairs depending on where I'm watching it. 

[koopie]

Jonny, yes.

It's actually more in line with how a higher end AV system works. I.e.  Connect all devices to the AV Amp/Receiver which in this case is represented by the Soundbar and then hdmi out to TV/display panel. A daisy chain if you will. 

As an aside I've seen some here say their Soundbar only has one hdmi in. To be accurate if it only has one hdmi port that's an hdmi OUT (to tv) not an hdmi IN port. You could say that's me being fussy but actually it's helpful to think of it that way to understand the process for yourself. It also helps confusion for techies as they could think that saying that there is 1 hdmi in to mean that this is in addition to the hdmi out port.

This isn't correct. 

Normally, for soundbars with a single HDMI port, the port is ARC or eARC so is therefore designed to be an INPUT from a TV.

No sorry you've got that wrong.

ARC simply means Audio Return Channel. So it's signal OUT from Soundbar and then the TV can send audio back to the soundbar through the same hdmi cable using ARC.

Also notice that the HDMI port that you plug the soundbar in to the TV is called an input. ARC, eARC or otherwise.

Sorry, but I'm not wrong.

A single HDMI port on a soundbar is designed for receiving audio from a TV via ARC or eARC.

Any audio from the TV, be it from its built in Freeview/Freesat/Freely service, or from any device attached to the TV's other HDMI ports is sent from the TV to the soundbar. 

What would the soundbar be sending out of that single HDMI port if there is no other input? 

This may help to describe how ARC and eARC works:

You are wrong sorry.

ARC simply allows audio that is coming from the TV or devices connected first to the TV to be RETURNED through the hdmi in cable from the soundbar. The soundbar itself is a device that you are connecting to the TV. 

The confusion admittedly lies in the fact that manufacturers due to the advent of ARC eARC  have stopped adding HDMI inputs to the soundbars (cheaper to build) and purely relying on ARC feature and solely using the TV's HDMI in sockets for devices.

Sorry, but nothing about what I have stated is wrong. 

I have 25 years of working in the A/V industry and know how ARC and eARC works. You need to think about it in terms of the direction of the signal being sent.

A soundbar with a single HDMI port will use that ARC HDMI port to receive audio from the TV's ARC HDMI port. 

A soundbar with multiple HDMI ports will use its HDMI INPUTs to receive audio and video from other devices (such as a Stream puck, Firestick or BluRay player) and use its ARC HDMI port to output the video (and audio, though it's not necessary as you are using the soundbar to actually hear the audio, not the TV speakers) to the TV.

Any other device attached to the TV or from its internal tuners/apps can be sent to the soundbar via the same HDMI ARC port, even though it is not labelled as an HDMI INPUT, it receives the audio sent from the TV.

Your mistake actually is that you are looking at it in a purely audio direction way. 
The physical eARC port in the back of the soundbar is technically an output to TV that can receive RETURNED audio through the very same device input cable. Now to make things simpler for people they tend to just call HDMI ports that carry ARC  as just simply HDMI ARC/eARC and drop the in/out labelling., as I say to make it simpler to understand. 

[Paul+Dray]

This image here for instance is the back of the latest Sony Bravia Soundbar that shows the eARC/ARC port as HDMI OUT:

[Paul+Dray]

And no it isn't just called that because this soundbar has an hdmi in as well. Regardless of whether it would or not the hdmi to tv port on the soundbar is technically always an output. 

this is even the guidance from Sony's how to page:

How to connect a sound bar directly to a TV

1. On the back of your TV, look for the HDMI input slot labelled ARC (Audio Return Channel), or eARC (Enhanced Audio Return Channel). 
2. On the back of your sound bar, find the TV OUT (ARC) slot. 
3. Connect both slots with the HDMI cable.

It is not a mistake. The key to understanding how ARC and eARC works is to work out the direction of signal transfer. 

I'm not quite sure why you are fixated on the RETURN aspect of the Audio Return Channel. 

Look at the specs on this basic Polk Audio soundbar at Richer Sounds with a single HDMI ARC socket:

https://www.richersounds.com/polk-audio-react-black/#tab-specifications 

It describes the inputs available as HDMI ARC and Optical Digital. If you search for the user manual this is confirmed. You press the TV input select button on the remote to hear the audio being received from the TV. It is not being returned to the TV via the same cable. What is the point of it doing that? It's already coming from the TV so it doesn't need to be sent back to it.

You still don't understand. I'm not saying it's returning from the soundbar to the tv. The RETURN is the audio being RETURNED from the TV to the soundbar via the HDMI cable connecting from the soundbar device into the tv. Think of it this way. If a soundbar only had one hdmi port and it was an hdmi in then there is no need at all for ARC/eARC as just a standard TV HDMI OUT port to a Soundbar HDMI IN port would suffice to carry audio from tv to soundbar. Which is why ARC/eARC on a soundbar is always technically an output first and foremost that can receive audio back. 

as I said before a lot of these manufacturers use different terminology in certain contexts to make things simpler for people to understand.
