I'm trying to connect several bluetooth devices with Raspberry PI to use them as speakers.
I'm using RetroPie as a distribution, because of the tests I've done, it's the only one that matches and allows continuous synchronization with several bluetooth devices at the same time.
However, the system only detects the first device that connects as a sound card, the rest keep the bluetooth synchronization active, but it does not interpret them as audio cards although it is indicated by blueman-manager .
Is there anything I can do to keep all the devices synchronized and supported as audio cards?
