Can someone who uses Chromecast with M3 tell me which "cast firmware version" (not "system firmware version") is at the bottom of the speaker settings in Google Home? Maybe make sure that the M3 is up to date beforehand, i.e. go via the B&O app. Reason for my question: My M5 is behaving strangely. Compared to my Google Chromecast Audio, it doesn't turn down the volume when I talk to the Nest Mini (= Google Assistant), and it's separate from all the other Google speakers in the Google Home when music is playing. I.e. if it plays on the M5, I can't add the Chromecast Audio, and vice versa. Google with each other works great. At over 500.- I expect more on the SW side too. M5 (from 2017) Cast firmware version: 1.28.102057 Chromecast Audio (from 2015...): 1.42.172094 As a comparison, the last version of the very first Chromecast from 2013: 1.36.xxx
