How to play audio on multiple devices on your Ubuntu machine?

List sources

$ pacmd list-sources |grep name:
	name: <bluez_sink.00_00_00_00_D2_89.a2dp_sink.monitor>
	name: <alsa_output.pci-0000_00_1f.3.analog-stereo.monitor>

List sinks

$ pacmd list-sinks | grep name:
	name: <bluez_sink.00_00_00_00_D2_89.a2dp_sink>
	name: <alsa_output.pci-0000_00_1f.3.analog-stereo>

We want to replay audio coming out from bluez_sink.00_00_00_00_D2_89.a2dp_sink.monitor to alsa_output.pci-0000_00_1f.3.analog-stereo

$ pacmd load-module module-loopback source="bluez_sink.00_00_00_00_D2_89.a2dp_sink.monitor" sink="alsa_output.pci-0000_00_1f.3.analog-stereo"

To remove the replay to other device we just created above, we can unload that module:

$ pacmd list-modules | grep name: | grep loopback
	name: <module-loopback>

$ pacmd unload-module module-loopback
$ pacmd list-modules | grep name: | grep loopback
