For a headless server using @emph{bluealsa} with a fixed Bluetooth device is likely simpler than configuring Pulseaudio and its stream switching behavior. We configure ALSA by crafting a custom @code{alsa-configuration} for the @code{alsa-service-type}. The configuration will declare a @code{pcm} type @code{bluealsa} from the @code{bluealsa} module provided by the @code{bluez-alsa} package, and then define a @code{pcm} device of that type for your Bluetooth speaker."
