    This gist will show how to setup a generic SBC Debian / Ubuntu install as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

    ## Motivation
    A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:
    * Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
    * Simple - This solution has few dependencies, readily available packages and minimal configuration.
    * Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43
    This is forked from another gist specific to the Raspberry Pi on Stretch. Several required packages aren't in Ubuntu's repos, so in this gist we build them from scratch.

    Tested to be working on Armbian/Ubuntu/Debian images of the Orange Pi Zero, ODROID XU4, ODROID N2, and Atomic Pi.

    ## Prerequisites
    * Raspbian Stretch - I used the Lite version as this is a headless setup. See the [official guide](https://www.raspberrypi.org/learning/software-guide/quickstart/) if you need help.
    * [Bluez-alsa](https://github.com/Arkq/bluez-alsa) - Available in the Raspbian package repo. This software allows us to stream A2DP audio over Bluetooth without PulseAudio.
    * Raspberry Pi with Bluetooth - The Raspberry Pi 3 has integrated Bluetooth, however there is a [known bug](https://github.com/raspberrypi/linux/issues/1402) when the WiFi is used simultaneously. Cheap USB Bluetooth dongles work equally well.
    * A linux SBC running Debian or Ubuntu
    * Bluetooth Dongle or integrated Bluetooth. Sound card (internal or external) that is known to work with Alsa.

    ## Disabling Integrated Bluetooth
    If you are using a separate USB Bluetooth dongle, disable the integrated Bluetooth to prevent conflicts.
    # Auto-Install Script

    To disable the integrated Bluetooth add the following
    ```
    # Disable onboard Bluetooth
    dtoverlay=pi3-disable-bt
    ```
    to `/boot/config.txt` and execute the following command
    ```
    sudo systemctl disable hciuart.service

    * Raspbian Stretch - I used the Lite version as this is a headless setup. See the [official guide](https://www.raspberrypi.org/learning/software-guide/quickstart/) if you need help.
    * [Bluez-alsa](https://github.com/Arkq/bluez-alsa) - Available in the Raspbian package repo. This software allows us to stream A2DP audio over Bluetooth without PulseAudio.
    * Raspberry Pi with Bluetooth - The Raspberry Pi 3 has integrated Bluetooth, however there is a [known bug](https://github.com/raspberrypi/linux/issues/1402) when the WiFi is used simultaneously. Cheap USB Bluetooth dongles work equally well.

    * Set the DiscoverableTimeout in ``/etc/bluetooth/main.conf`` to 0
    1. Set the DiscoverableTimeout in `/etc/bluetooth/main.conf` to 0
    ```
    # How long to stay in discoverable mode before going back to non-discoverable
    # The value is in seconds. Default is 180, i.e. 3 minutes.
    # 0 = disable timer, i.e. stay discoverable forever
    DiscoverableTimeout = 0
