[Buildroot] [PATCH v2 1/1] package/bluez-alsa: allow a samplerate conversion for audio playback

[Charles Hardin]

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.
