bluez-alsa (Bluetooth Audio ALSA Backend)

This project is a rebirth of a direct integration between Bluez and ALSA.
Since Bluez >= 5, the build-in integration has been removed in favor of 3rd

audio application, which implements Bluetooth audio profile, and a Bluetooth
audio device.

Note: you might want to "start" "/usr/bin/bluealsa" via rc.local --
for example, add the following line to rc.local:

  /usr/bin/bluealsa &
