Risking major flames here but .. my Sonos amps do this perfectly. Analog cable through the house, amps on eth in the media closet, it’s is very very solid.
Yeah, that's why I added the caveat at the top of my rant.
Too bad they messed up the app so badly. I've written some hardware-control applications and they're not necessarily easy, but... well, that's the job.
Meanwhile I've had my time stolen on numerous "ghost job" postings. Maybe someday, somewhere someone will take a lesson from Boeing and Sonos and other companies that have suffered from grossly incompetent software engineering and put a halt to the despicable disrespect for our time and knowledge.
Also I hate the new app with fiery passion
