Lip sync delay when TV audio is cast to speaker group

[summer_buns]

I have one nest audio and several nest minis grouped in my google home app. When I cast my TV to one speaker, there is no lip sync delay. But when I cast my TV to the speaker group, there is a huge lip sync delay. I've tried correcting the delay through group delay correction, but it doesn't help. Any advice?

Hi summer_buns,

Thanks for posting here in the Google Nest Community.

Are you playing the audio from your TV to the speakers via Bluetooth? Could you give us more details about it, so we can better understand your concern?
 

Looking forward to your response.

Regards,

Juni
