Hello.
My setup is Volumio (System Version 2.713) on Raspberry Pi 3+ with Hifiberry DAC+ Pro.
I’m using Spotify Connect, and Volumio as a media player for my home automation setup (Home Assistant=HA). HA is running on a different RPI3+ From HA I’m trying to stream mp3-files (Text-To-Speech announcement) to Volumio while Spotify might be playing, so those two streams need to mix together.
My working setup would do this:
- Spotify playing at 100% volume
- TTS coming to Volumio
- Spotify volume down to 50%
- TTS announcement mixed together with low-volume Spotify
- Spotify back to 100% volume
Currently Spotify is working fine, and so is the mp3/TTS streamed to Volumio… But, whenever I send a mp3-file to Volumio, Spotify will get paused. Volumio is kind of changing the source from Spotify to mp3-player (MPD maybe?). I need the mp3 to play/mix over the Spotify. How I could get this working?
