I understand that the IdPi's bluetooth is disabled, so it's not possible to directly play via bluetooth to a BT speaker, or some other output like that. I was wondering though if an external (USB) BT sound card would work. Would that show as an external audio device then? I see good application for the IdPi to play to a Google Home or Amazon Echo, but neither has an aux in. Anyone tried that, or do you think it's worth trying? Thanks for the input!
