I use a mix of Chromecast Audio, Chromecast video, and Google Home devices of varying vintage. The Chromecasts are the audio source to a TV and a handful of stereos in different rooms, some with really old gear. The Google things can be grouped across types. They used to be unreliable, but before I could get annoyed enough to get Sonos gear, Google seems to have fixed the problems. I have whole house audio with relatively little at risk of being EOL'ed, and individually pretty cheap to upgrade if eventually needed. The key thing is: Audio is not a moving target. My Klipsch speakers are over 40 years old. They are connected to a McIntosh receiver I found literally on the scrap metal pile at the town dump. This seems to be a more resilient approach than either going 1970's analog with wiring in the walls, or buying a suite of proprietary speakers with audio distribution built in. The expensive bits have an indefinite lifespan. Sonos decided to combine that with microprocessors, NICs and software that, they discover, has to have the lifespan of a PBX or airplane control panel, not a mobile phone.
