Hello!
Looking to build an Amp that drives two speakers and allows me to control Spotify via Google Assistant / Google Home.
To this end it seems like there are three options:
1) Software on the HifiBerry that can be added as a skill to Google Assistant
2) Software on the HiFiBerry that represents a Chromecast endpoint, so that Google Assistant can cast to it
3) A Chromecast stick that I plug into the HDMI port of the RP4, then cast to this stick and play music from this source. Alternatively I read about connecting the Chromecast via TOSlink...?
Which of these options is feasible?
Another option: Is the HifiBerry able to automatically switch sources? Say I'm playing web radio via the integrated software, then cast Spotify, then back to web radio. Asking because I want to run a headless setup.
Thanks a lot in advance!
Best
Julian
