I do not know anything about chrome-cast so hopefully my question is valid.
I was thinking if I could hook up a chrome-cast enabled device to the digital input of my amplifier then I should be able to cast audio from my phone to the amp in other words:
stream (cast) music playing on my android phone from a streaming service (adagio or amazon) to my amplifier using a digital output (or USB)
It seems that chrome-cast audio does not have digital output. And chrome-cast requires HDMI-enabled TV.
Is there a chrome-cast alternative with digital output (or USB)?
