Unfortunately not. I use LMS for music now, which renders my previous setup redundant. I used that for Google Cast service calls which I no longer use.
But basically what you see there is:
- Input select playlist
- Input select speaker
- Script to start service call for selected playlist over the selected speaker
- My custom media player based on picture elements and mini media player (see this)
This all inside a vertical stack, which opens through popup with browser mod.
