The use of a bluetooth device as an audio input in 4a must be implemented ASAP.

What is needed :

• Development of a '4a-hal' controller plugin that will get the connected bluetooth device. It must register itself to AGL bluetooth network service (provide by connectivity) to stay informed of the connected bluetooth devices.
• Provide the bluetooth hardware address to 4a-softmixer.
• Creation of an input PCM using the received bluetooth hardware address in '4a-softmixer' (an example is available in 'bluealsa-aplay').
• Use the previously created PCM to stream audio from the bluetooth device to speaker output.
