Pff partially working. No PID. When setting the audio clock on the bbb to 44098 the master and slave clock keep diverging instead of converging ...

The D-Box code can be built on the board using the scripts included with
BeagleRT. To build the code, do the following from the scripts/ directory:

./setup_board.sh    # Only if BeagleRT is not already copied to the board
./build_project.sh -n ../projects/d-box  # -n means don't run yet

You will now need to copy the .dbx sound files to the box. These need to
be in a directory: /root/d-box/sounds

Log into the board via ssh to create the d-box directory, or run:

ssh root@192.168.7.2 "mkdir /root/d-box"

Now copy the .dbx files from a source of your choice to the board. Assuming
they are in a directory called "sounds":

scp -r sounds root@192.168.7.2:/root/d-box/

Now you can run the D-Box program to make sure it plays. You will need the
sensors and matrix connected to the box (i.e. a complete hardware D-Box).
From the scripts/ directory:

./run_project.sh -f -c "-q 24 -r 25 -t 2 -s -p 2 -l 0 -u 0 -i 1 -n f -g 3 -v"

If this plays properly, the D-Box can then be set to run automatically on boot:

./set_startup.sh -l -c "-q 24 -r 25 -t 2 -s -p 2 -l 0 -u 0 -i 1 -n f -g 3 -v"

If at any time you want to stop the D-Box program running, you can run:

./stop_running.sh

To turn off further autoboot, run:

./set_startup.sh -n
