Feature-Request: Play sound via api

A lot of people are searching for audio feedback in their smart homes. There are a lot of different solutions for that. e.g. SONOS.

For example: When you enter the room, you want to get a list of open tasks / whats happening today. Or someone rings on the front door, you could also play a sound over your vaccum without a seperate speaker in that room.

Obviously I want to play my own sound files. Maybe valetudo could offer an upload mechanism on the web UI to make that process easier. What I need for that task, is an API which can be used to trigger the playback.

At the moment I could use ssh to start the playback. But that’s not the nicest solution ????
