HomePod mini sound delay

Just received my HomePod mini. Sounds great. A little disappointed that it won't just play BBC Radio channels unless I airplay from my iPhone using the BBC Sounds App. However I can live with that. What I can't live with is about a 2 second delay in the sound when using any video conferencing app on my Mac: FaceTime, MS Teams and Zoom all have a terrible delay which causes really bad eco for others on the call.

I am running Monterrey Mac OS 12.0.1
