Configuring the Beaglebone Black to run Squeezelite
Entry posted by k-man
Getting the Beaglebone Black was only supposed to be a fun lesson in following a set of Linux instructions for audio playback, and assessing the merits of embedded systems with low power requirements. The results were convincing enough to share for the first blog, and this next set of instructions is an alternative configuration that will appeal to those who are finding MPD and network mounts to be too complex. With the Squeezebox Ecosystem, the NAS/PC/Mac runs Logitech Media Server and the Beaglebone Black is the client/renderer that runs Squeezelite, and is connected to the USB DAC. If all the hardware is connected according to the “Geek Speak” article, then it’s a simple case of installing the software.
Installing Logitech Media Server (LMS):
My Media - Welcome to mysqueezebox.com!
Some NAS like Synology have management software with the option to install LMS as an App. Run the software, and under Settings add your shared music library to the LMS Media Folder (browsing the folders makes this easy). Scanning the media files initially can be a rather lengthy process for big libraries, but the cached database is stored on the server’s side (instead of the Beaglebone), which is a lot more convenient on startup.
Installing Squeezelite on the Beaglebone Black:
If the instructions for installing MPD in the previous article were completed, then installing the squeezelite libraries won’t be necessary. Otherwise:
sudo apt-get install libasound2-dev libflac-dev libmad0-dev libvorbis-dev libvo-aacenc-dev libfaad-dev libmpg123-dev
wget http://squeezelite.googlecode.com/files/squeezelite-armv6hf
sudo mv squeezelite-armv6hf /usr/bin
cd /usr/bin
sudo chmod u+x squeezelite-armv6hf
./squeezelite-armv6hf –o hw:CARD=1,DEV=0
Now look for the Player in LMS under the Player tab and start browsing your music. For remote apps, Logitech’s own Squeezebox Controller App is free, but iPeng is well worth the premium for a more responsive and intuitive experience, especially those with huge libraries.
Squeezelite Startup
This will start up squeezelite on boot, to give the Beaglebone a 'Toaster' operation. The original script is from a Raspberry Pi thread: Raspberry Pi • View topic - Squeezelite up and running on Raspian Wheezy Hard Float
To create the startup script:
sudo nano /etc/init.d/squeezelite
Cut and paste this entry into /etc/init.d squeezelite
#! /bin/sh

Save and close the script. To make squeezelite executeable:
chmod +X /etc/init.d/squeezelite
Test it.
sudo ./squeezelite restart
To check if squeezelite is running:
ps -A |grep squeeze
This adds the script to boot.
