Hey all,
My goal was to create a sort of surround output (mostly for music) at the same time (in the same room). So I could still use both speakers and have more and fuller sound in the room.
The good news is that after 2 nights of fiddling it works! 
Older topics helped me allot to get it working
The bad news is that there is a delay of 2-3 seconds between the speakers, which makes listening to music uncomfortable. The homepod is always ahead of the Teufel with RPI.
My setup:
- A new Apple HomePod Mini
- Teufel Ultima 20 Kombo (my old setup), connected via RP4
Can’t really find any solution via the forum.
Guidance is much appreciated!
Kind regards,
Theo
