In my home, I have been able to play music via Apple airplay to multiple speakers. My setup consists of 1 HomePod, 2 HomePod Minis, 1 AirPort Express, and 1 TCL Roku TV. The audio synchronization across all of these devices at once was perfect, not a single issue. Until now.
it seems that the Roku TV is 1/3 of a second behind the rest of the speakers (aka it’s not in sync with the rest). I can isolate the issue to the Roku TV because none of my other speakers are experiencing this.
I have tried resetting the TV audio and picture settings. I have tried factory resetting the TV. The issue still persisted afterwards.
I also tried restarting my router, restarting all of the other speakers, disconnecting my sound system from the TV and using the TV speakers. No luck 😕
All HomePods are on WiFi. AirPort Express is on Ethernet. Roku TV is on Ethernet. TV has a basic sound system hooked up via 3.5mm (headphone jack) to RCA
