Google nest sync on LG TV sound

Hi

My LG TV has perfect lip-synch sound when listening with my bluetooth headphones but is vey out of sync when listening on a paired pair of Google Nest speakers. Can this be sorted?

I've been looking for a solution to this myself. So far I haven't found one. I've read a span of about 4-5 years worth of conversations about it. Mostly on Reddit. Seems like this is a problem that google just really doesn't care to  fix. It seems like it wouldn't be that hard for them to correct with an update of sorts. I just bought about 8 Nest Minis and I'm pretty disappointed about this myself.

Have you both looked into the group delay correction that's available in settings under each speaker's "Audio" heading in the Home app? I'd also take a look in your TV settings, there may be an audio sync adjustment there as well after all sound is processed there before being sent out to the speakers. Don't know if it will fix it or not, but the option is there and that's what it's supposed to do. Bluetooth may work flawlessly because it has lower sound quality to begin with, not to mention the secondary compression that happens in order to transmit the file when compared to WiFi.

Sound sync issues can be caused by any number of things, the broadcast signal, interference with the method of connection, audio processing delay (internal to the device sending the signal) or even issues with pulse code modulation (the process of converting analog audio to digital audio). Not to dodge the issue but, the Nest speaker simply receives what it's sent; processing happens upstream. The adjustment in settings may, hopefully, be able to correct and compensate for all that.

It's odd to me is that if I Bluetooth to a pair of headphones, there is no audible delay. If I bluetooth to my Google speakers, there is a very large delay. Over a second I would say. This tells me that the problem lies with the Google speakers, not the tv or anything else. Right?

Maybe not but if I had to make a bet, my bet would be the speaker was designed for WiFi for better performance, not Bluetooth because it's slow and because of the double compression that goes on with Bluetooth. The control I referenced earlier is for Wifi, and is not designed for managing Bluetooth delay.
