3.5mm plug and bluetooth multiple output

[Tim Curtis]

It can be hacked but the music will not be in sync at the 2 endpoints. This is why it's not a built-in feature.

The hack is to enable MPD output 1 via SSH after connecting to Bluetooth speaker and setting to MPD audio output -> Bluetooth in BlueZ Config.

Code:

mpc enable 1

You could also toggle between the two outputs by the commands below without having to disconnect your Bluetooth speaker. 

Code:

# Switch to Default output
mpc enable 1 && mpc disable 6

# Switch to Bluetooth output
mpc enable 6 && mpc disable 1

# List MPD outputs
mpc outputs
