I’m using the web app in Google Chrome on Windows 11 and casting to a Chromecast Audio. It works fine, but disconnecting the Chromecast, either manually or automatically (I think it disconnects automatically after about 15-20 minutes), the stream starts up again locally once the connection to the Chromecast device is disconnected. This happens even if the music was previously paused using the controls in the web app. The only workaround is to use the media controls in Chrome; when you pause the stream there and the Chromecast disconnects sometime later, the stream does not resume.
The main issue is that I paused my stream and started a virtual work meeting, only to hear my music start playing for everyone on the call to hear about 15-20 minutes later. I wanted to report this issue, as it would be nice if the music is paused that it doesn't automatically resume after a Chromecast disconnect event.
