I'm currently building an integrated amplifier based on a Hypex DLCP system and 6 channels of Hypex UcD amplification. As a long-time Squeezebox fan I'm also building in a Raspberry Pi 3B+ running pCP into the enclosure. This will be connected permanently to the single USB input on the DLCP.
I thought it could be fun to add some kind of Bluetooth receiver to the amplifier. I know I could get a simple Bluetooth-to-3.5mm jack adapter (I have a couple already) and use one of the DLCP analogue inputs. But it occurred to me that the RPi already has all the necessary hardware to do this, so maybe there's a software solution out there to allow the RPi to receive audio on its built-in Bluetooth and redirect the stream to the USB. Is anyone aware of something like this?
One major constraint is that the USB output will normally be assigned to the pCP Squeezelite, so to get this Bluetooth approach to work I think I'd have to temporarily stop Squeezelite and start the Bluetooth 'transceiver', so probably not a 'smooth' option. Is it possible that Squeezelite and this notional Bluetooth transceiver software could both output to the USB device at the same time, or would one make it unavailable to the other? If both could be connected simultaneously, all I'd have to watch for would be to make sure that only one source was actually playing at any one time.
