Hi @RolandasR, what issue with Spotify volume do you have?
I meant the volume control of lullabies. The app is set to lower volume during the specified time until it is off. It works well if the lullaby is played on phone but it doesn’t if I play them on TV. Lowering the volume manually from phone just works fine, but the app cannot control it, although it displays a bar at the bottom of the currently playing lullaby. The phone volume bar has a cast symbol on it, so perhaps, the app needs to set some option and it would work as well.
The lullaby volume controls the media sound stream. Is the Spotify casting via a different stream, when you connect it to the TV?
I tried both. You can stream from phone or start playing standalone on TV. In both cases volume control on phone changes to casting mode, perhaps Spotify knows when it is played on TV. And Sleep as Android sees it as playing in both cases. But it cannot control the volume then.
