The Samsung integration sees my speakers but has a process that cannot be done on the speaker as it is not a TV. I really would like my speaker(s) to be integrated so I can use them for TTS and music.
Today I released the first non alfa version of my custom component that makes it possible to integrate Samsüng Multiroom Speakers, like the M5 in Home Assistant. I have two M5 my self (besides M3, M7, R1 and R6), and love the sound in them!
