Hello, I’d like to introduce you to this forked, working, and actively being improved Sonos Card: Lovelace: Sonos card
This OTHER thread has tons of examples and folks willing to help you with the SONOS card. I’m glad you got it working, but a word to the wise: the 2022.5 beta version of HA has introduced breaking changes for this card which will render the display of your card useless. This has been reported and the author is aware. You’ll be fine as long as you don’t download 2022.5 before we get a fix for the card.
You can follow along with the state of that fix in the other thread. If you post questions about sonos in that other thread, you’re very likely to get an engaged response.
