In the case of the bluetooth audio then incoming stream will be coming from bluetooth devices at varying sample rates like (44.1, 48, 96, 192 kHz) and the odds of a sound device matching that samplerate exactly is a bit slim. So in the case of a bluez audio playback the system will need to do a samplerate conversion. Thus when enabling bluez-alsa and the alsa plugins select libsamplerate to support the shift from the incoming samplerates to an often fix-rated audio device.
