In 'Boot Options' -> 'Console AutoвЂ“login'. Some people complained that the whole configuration does not work after reboot, unless pi user is logged in.ДЄutoвЂ“login can be enabled using raspiвЂ“config utility $ sudo raspi-config Note: Observe connection log 'live' to debug connection issues: $ tail -f /var/log/a2dp-autoconnect I located it in /home/pi/a2dp-autoconnect, then made it executable: $ chmod +x a2dp-autoconnect

It's pretty straightforward: it redirects a new Bluetooth audio source to the right sink and sets output volume level. The script I used is an extended version of. KERNEL='input*', RUN+='/home/pi/a2dp-autoconnect' Add udev rule which executes a2dp-autoconnect script each time a Bluetooth device is connected: $ cat /etc/udev/rules.d/les In the above case, it would be bluez_source.A8_88_08_11_AB_4B to alsa_output.0.analog-stereo. smartphone) the right sink (ALSA) each time a new Bluetooth device is connected. The whole trick is to redirect the right source (i.e. Given that your device is already paired and connected to PI, run the following: $ pactl list sources shortД alsa_output.0.analog-stereo.monitor module-alsa-card.c s16le 2ch 48000Hz IDLEДЎ alsa_input.0.analog-mono module-alsa-card.c s16le 1ch 48000Hz IDLEД¤ bluez_source.A8_88_08_11_AB_4B module-bluez5-device.c s16le 2ch 44100Hz RUNNINGД alsa_output.0.analog-stereo module-alsa-card.c s16le 2ch 48000Hz RUNNING Then, for each device: pair XX:XX:XX:XX:XX:XXД¬TRL(CMD)+D to exit bluetoothctl. See that your USB dongle is here: # listД¬ontroller 00:1A:7D:DA:71:06 raspberrypi Pair devices (phones, tablets, PCs) with PI using bluetoothctl utility: $ bluetoothctl But I added it anyway: $ cat /etc/bluetooth/nf

I'm not quite sure if the following is also needed. Make sure Bluetooth audio is working and discovered as a car audio system $ cat /etc/bluetooth/nf Options snd slots=snd-usb-audio,snd-bcm2835ДЇrom now on RPI uses USB Audio as default: $ cat /proc/asound/modules # This sets the index value of the cards but doesn't reorder. Some configuration does the trick ( related article): $ cat /etc/modprobe.d/nf The problem is that onвЂ“board audio ouput is prefered over USB audio interface: $ cat /proc/asound/modules So if you expect PI to do something else beside A2DP and avoid sound glitches, reasearch different resample-method. With the following configuration it uses ~30% of my PI's CPU. Use the following configuration to get most of PulseAudio ( related article): $ cat /etc/pulse/nf Not quite sure it's really needed (?), but it doesn't hurt: sudo usermod -a -G lp pi

Make sure your system is upвЂ“toвЂ“date first: sudo apt-get update I'm using Raspberry PI 1 Model B, running Raspbian Jessie. Google to learn more, it's a very common topic when using Raspberry PI. You'll need some active (powered) USB Hub to keep USB devices stable and working (USB Audio, USB Bluettoth and optional USB WiFi). Raspberry PI offers limited power to USB devices (and limited number of ports).

Trial and error is another option, since most devices cost below $10. See RPi USB Bluetooth adapters for buying recommendations. This way or another, if you get garbled audio or no audio at all but everything else is alright, don't worry, just try another dongle вЂ“ it's cheap.

Or they pretend to use the same hardware for some (compatibility?) reasons. So beware, because different manufacturers use the same hardware in a different way.

Note: I used another dongle (different manufacturer) also discovered as Cambridge Silicon Radio but unable to stream audio. Bluetooth dongleДЄs for Bluetooth dongle, I used Digitus Tiny USB-Adapter, which is discovered as Cambridge Silicon Radio, Ltd Bluetooth Dongle. I chose external USB Creative Sound Blaster Play! interface. The onвЂ“board audio produces lowвЂ“quality, noisy output, so I decided to use something better.

It's like a regular car audio system, but it can be used anywhere and it's a good value. This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers.
