This might be “just me” in terms of the way our setup is configured, but humour me none-the-less!
The Aura is connected via HDMI to the Panasonic TV, and then HDMI from the TV to the soundbar. It is also connected via optical from Aura direct to the soundbar.
THis is because sometimes the TV appears to introduce sound delay (not all of the time, but often after switching between an IP channel and “normal” viewing). When the audio is coming directly from the Aura over optical the delay disappears.
That’s not a huge problem for me; it’s an old-ish TV and a cheap soundbar, so for the sake of pressing a button every now and again it works fine.
One mild annoyance though is when switching back (say) from Disney+ to Freeview the soundbar is triggered to return to the HDMI input, rather than just stay on the optical selection.
Is this just a peculiarity of the way I’ve got things configured?
Got some questions/info from the programmer for you:
1. It will be helpful to know which app he is using. (Disney+, iPlayer, … )
2. As user is not in firmware group, I think it’s worth to try to change audio setup.
•Settings > Device Preferences > Sound > Select formats > None.
The change will make audio output as PCM, I think it may work for his case. As you know, new firmware will include easier settings of audio.
3. I’m curious about the symptom the user has. The audio is late when problem happens or the opposite.
Just get rid of the hdmi between the TV and the soundbar.
Just have Aura>TV hdmi then TV>soundbar optical.

A perfectly sensible suggestion – but the problem is then other devices through the TV don’t route to the soundbar (e.g. xbox, Chromecast) and would have to use TV speakers only.

They should.
The optical from the TV will be carrying the sound corresponding to whatever is on the screen, live TV/Humax/Xbox etc, it really does not matter. That’s how it has worked on every TV/soundbar I have set up in the past.
And if yours doesn’t, I would suggest looking in the TV settings (either sound or optical/spdif controls) and see if there is an option to passthrough ALL inputs.

Thanks for playing this to the programmers Barry.
1 – I’ve not correlated any relation between any of the apps specifically, but I use primarily iPlayer, Disney+, Eurosport, All4 and the sideloaded NowTV. However, I have isolated this as being a TV problem, not an Aura problem so I’m not sure if the devs need / want to get into this.
2 – I’ll check what sound settings I’ve selected; I think I’d previously selected a mode which ensured I was using PCM but I’ll do as suggested above and report if that is different to what I already have established
3 – Symptom is audio delayed behind video when it happens. But as per answer to 1 I’m pretty confident that this is an issue introduced by the TV; whether the TV is prompted into it by the Aura I can’t say, but I can say that if I use optical instead it immediately resolves the sync issue.

Surely not if the optical is directly connected between the Aura and the soundbar? The Aura would have no connection with the Xbox / Chromecast etc so surely it couldn’t output those device’s audio over the optical lead? I could route the aura’s optical into the TV and see how that gets passed through through, so I’ll look into that.
That’s not what I said in post #3
Aura>TV hdmi (plus any other equipment)
Tv>soundbar optical
Also, based on what you said in your first post about the soundbar, I will hazard a guess that it is 2.1 maximum.
So there is absolutely no advantage in having any of your devices set to output anything other than PCM.
Or the other option (assuming your TV has hdmi-arc, is :-
All devices>TV hdmi
TV>soundbar hdmi-arc.
In other words, no device needs to be connected to the soundbar twice.
Aha, should have read more carefully.
I think I’ve avoided Aura > TV-HDMI, TV > Soundbar-Optical because that means I need to power up and power down the soundbar manually each time with a separate remote, but I will try again in case I was misunderstanding.
@barry – I’d previously selected “Stereo” only in the Freeview “Audio & Video” menu, but on checking the Android “Sound” menu I can see that DTS remained selected, so I’ve unselected that to see if that makes a difference. Having the settings in two different places creates a small amount of scope for confusion, but I suspect it’s unavoidable.
As I mentioned previously, feeding anything into either your TV or your soundbar that is anything other than PCM (stereo) is pointless because it then means that either your TV or your soundbar then have to downmix the 5.1 into 2 channels,which takes time, milliseconds of course, but that’s where lipsync issues can arise.
Yep, I knew that about the Dolby / surround stuff. I hadn’t intentionally left it on, just not spotted that there was a separate option outside of the “audio & video” option to select.
I’ve now plugged the optical cable directly between TV and soundbar and disconnected the hdmi arc from the soundbar. My only hesitation with this is that I lose the ability to adjust volume on the soundbar itself, and I worry that the standby behaviour of the soundbar may mean that sometimes the TV turns on without firing up the soundbar which will annoy others in the family!
Xbox 360 though will require volume intervention with the soundbar remote which will be irritating as it’s a tiny remote, though in fairness buttons are in the soundbar too.
I probably should also have given time to see if the simple step of disabling that DTS toggle would actually cure the issue I had, but if optical works I can live with it.
Thanks for the interest in this though, it’s been helpful!!
