PRINT version of "Gear4 BlackBox Mini External Speakers Linux HOWTO"
    <= Back to SCREEN version <=

This is a small documentation about how to use Linux with the BlackBox Mini external BlueTooth A2DP speakers made by Gear4. Note: there are many different guides around about getting external BlueTooth speakers or headsets to work with Linux. To me it occurs as there have been some different approaches in the Linux Kernel for (ALSA) sound as well as BlueTooth.



My configuration:

  I have used BlueMan(http://blueman.tuxfamily.org/) to set the PIN, which is configured by the manufacturer to 1234, do the BlueTooth pairing (this tool calls it bonding) and setup the audio device. See the screenshot besides.





Now you are able to configure the Amarok sound devices. Set mono as well as stereo to bluetooth. Note the previous setting, in case you need to switch back. That's all to get Amarok playing sound via the external BlueTooth speakers. Though I found no way to change the volume, neither with ALSA volume control nor with the hardware buttons on the box. Sometimes Amarok hangs. And the configuration has to be started from the beginning. Also you can't use the buttons at the top of the speakers to move inside the Amarok playlist. The maximum distance to send data between the BlueTooth devices certified by the manufacturer is 30cm. I was able to transmit data about 3 meters. All in all I am not that satisfied with this speakers. I wanted to transmit the audio signal from my Linux laptop to the speakers into another room, but this doesn't work reliably.
