Hi I would like to know if it’s possible to receive audio data output from a Chromecast TV? My goal is to be able to play audio from Chromecast TV over my old analog speakers. Currently, chromecast allows for the connection of bluetooth devices, however, those devices have to be in “pairing mode”. I assume that this sends some sort of ping to the chromecast. I have tried pairing my rpi to it to no avail - the device is broadcasting BT.
Currently balenaSound only supports bluetooth as an input. We have a github issue open for adding a bluetooth output plugin, here: Bluetooth as audio out · Issue #323 · balenalabs/balena-sound · GitHub
I’ve added your vote to that issue.
