The receiving Bluetooth device which in your case is a Pi-1B configured to output to the integrated Headphone jack will output the PCM stream sent by your 3B to the Headphone jack or whatever device was configured in MPD Config.
Example
Pi-3B -> MPD -> Bluetooth Connection -> Pi-1B -> Bluez-alsa player -> Headphone jack
That's not quite what I am trying to do. I am only using the RPi 3B as a NAS Samba server to save duplicating the Music Library in the RPi 1B. The connection is not Bluetooth but over my WiFi Network.The distance between the two RPi units is too far for Bluetooth directly from the RPi 3B to the Speaker.
What I want to do is to add a USB Bluetooth Transmitter to the RPi 1B to output its MPD PCM stream to the Bluetooth Speaker without using the RPi 1B DAC. I have a USB Bluetooth 5.0 Transmitter which redirects the Audio stream when plugged into my Windows PC and I wondered whether it would be possible to configure the RPi 1B to do this.
I hope this makes sense ... Robin
If the USB transmitter declares itself to be an audio device then you should be good to go.
Example: I have a Creative Tech BT-W2 Bluetooth Audio transmitter.
In moOde's MPD Config panel, this shows up in the dropdown list of output devices. Select it and I'm transmitting audio to my Sennheiser BT headphones.
Note that the default plughw ALSA output mode is pretty much a necessity with this device since it recognizes 16bit /48kHz output rate only.
