ATTENTION!!
Always wanted to do that ?
I went to the Apple store yesterday and bought 2 HomePod Minis (Space Gray, of course) to go with my MBP14. I had previously ordered these, but cancelled them due to some people saying there would be an audio delay when watching video. I often use air-play to stream movies to my LG TV through the

tv box, and my LG connects to my Sonos audio system using optical. I've never experienced a delay, so I couldn't figure out why there would be a delay with the HomePod Minis.
I installed the Minis as a stereo pair yesterday, and I have streamed movies off Youtube, Netflix,

tv+ and other sources as a test, and the audio has been in good sync with the video. If there were any sync issues in the past, they appear to have been resolved as it's working on my setup. I'm running the latest Monterey beta, and the latest HomePod mini update. The sound is very nice. Good purchase!
