With the outages this week I have decided to revisit synchronized multiroom audio. The important feature for me is that it needs to utilize the “cast” button within the Spotify/Tidal/etc apps because that’s what my family uses.
Does anything exist other than the chromecast audio pucks?
The Google Casting protocol is proprietary (and indeed the outage was caused because the system that verifies a receiver’s “legitimacy” broke down lol) so AFAIK there is no Open Source solution that can replicate the functionality. At least so far.
