Home assistant TTS and other wav is chopped off

[sajov]

First of all, thank you for your project.
I have been trying to integrate my raufeld loudspeakers into a smart home assistant for years. Previously via rhasspy and node-red, now via home assistant. Now I realize that it is not so much a problem of the components but that apparently wav is not played back correctly in general. I have an automation in which I simply send piper tts to a Raufeld speaker for testing and it is always choppy, as with previous attempts.
Is it maybe due to sample rates or do you have any advice for me?

I have read the WIKI and thought setting a proper media_content_type music would solve my issue but i had no luck with this. Output is still chopped

I've been trying for a few years now to find out what the problem is or whether anyone already has a solution.
Has anyone integrated Raumfeld and run TTS with good results?
