Gstreamer or mopidy for audio out

Hi,

I’m working through setting up Home Assistant (HassIO) to play audio through. Reading this board there appears to be two paths, Mopidy vs Gstreamer to achieve these features.

The documentation of gstreamer was leading me to believe, by its omission of any explicit reference under Setup, that hassio wasn’t supported (or maybe no additional steps are needed?] [1]

The results documented for mopidy appear to show success [3], I have been pursing this but do not know if this extra add-on is creating unneeded complexity.

Is there a recommended path for using with Home Assistant?
