Picture of Bluetooth Speakers using Raspberry Pi
hi guys long time since i wrote a tutorial, this tutorial tells you how you can use any old speaker lying around your house into a wireless bluetooth speaker, this can also be an cheap bluetooth audio device receiver for your car. This is not my original work, but modified(added a few steps/changed a few) tutorial from http://kmonkey711.blogspot.com who has also taken help from Colin CW, i am reproducing this tutorial because this is the only tutorial that worked for me and i don't want it to disappear from the World Wide Web when i really need it. thanks Kmonkey for this awesome tutorial. Another way to have an wireless speaker is using AIRPLAY here

Step 1: What you need?

1 Raspberry pi (i am running Occidentalis_v02.img from adafruit)
1 speaker
1 Male-to-male 3.5 mm audio jack
1 bluetooth dongle ( check here for list of devices that work ) do check using the command hcitool scan
1 ethernet connection for pi/ wifi (how to connect a wifi dongle to Raspberry pi) (all u need to do is edit "/etc/network/interfaces" file)

I did all of the steps everything is ok (i share the music the PI is receiving the music) but when i put ''pactl list sinks short'' there is nothing there :( so i can't listen to my music

Can someone tell me why i cant see nothing after ''pactl list sinks short'' ? ? ?

Thanks, it worked fine. To connect your device using SSH:

install bluez-tools, a usefull package to use with bluetooth:

$ sudo apt-get install bluez-tools

Scan devices with:

$ hcitool scan

and take note the mac andress, something like XX:XX:XX:XX:XX:XX

Connect with your phone:

$ bt-device -c XX:XX:XX:XX:XX:XX

Choose a 4 number PIN, like 0000

Your phone will ask you to put this same PIN, do it.

Set your device to Trusted:

$ bt-device --set XX:XX:XX:XX:XX:XX Trusted 1

That's it, now you can continue with step 5.

PS: there's a little typo in step 5, in

$ pactl list sink short

it's really

$ pactl list sinks short

That's it, you can continue with step 5

Bluetooth speakers are fine but I would suggest its better to look for other alternatives before landing up on something. e.g. airplay or wifi speakers check out the differences between the two of them

A very useful DIY tutorial. Most especially when you have all of these parts hanging around your house.

I just added a USB-soundcard to the Pi.

with some changes in the sudo nano /etc/modprobe.d/alsa-base.conf and amixer cset numid=1 0 I can play songs which are at the pi, but bluetooth streaming doesn't work anymore.

What should I change, that the bluetooth streaming will work again?

thank you :)
Hey guys! I used the work here to build a much better version of a portable A2DP bluetooth receiver then what's provided here. Check out my guide!

After my smartphone is connected to the Pi i ALWAYS have to enter
pactl load-module module-loopback source=bluez_source.10_10_FF_2B_2B_2E sink=alsaput.platform-bcm2835_AUD0.0.analog-stereo

Is there a way to automate that ? And let it also work after a reboot ?!?

you could write a python script that would search for your device an connect it, i was trying to write one... i have attached the link to the code on git hub, if you could mod it ... u have to add

su -c "python /home/pi/Desktop/bluez/script.py" pi

in you /etc/rc.local file and..
comment /etc/inittab(sudo nano /etc/inittab)

#1:2345:respawn:/sbin/getty 115200 tty1
like this

#1:2345:respawn:/sbin/getty 115200 tty1
and add this below
1:2345:respawn:/bin/login -f pi tty1 /dev/tty1 2>&1

this would automatically startup bluetooth, search for your device for 3 seconds, if found it would link it to the ALSA audio else it would exit, u have to modify the code to work with your phone/device bluetooth MAC address. I am still working on the code, feel free to use the idea and make it work better.
