Mostly from http://elinux.org/BBB_Audio_Cape_RevB_Getting_Started
root@beaglebone:~# wget http://elinux.org/images/1/10/BB-BONE-AUDI-02-00A0.zip
root@beaglebone:~# unzip BB-BONE-AUDI-02-00A0.zip
root@beaglebone:~# apt-get update
root@beaglebone:~# apt-get install unzip
Compile the device tree file and move it to /lib/firmware:
root@beaglebone:~# dtc -O dtb -o BB-BONE-AUDI-02-00A0.dtbo -b 0 -@ BB-BONE-AUDI-02-00A0.dts
root@beaglebone:~# mv BB-BONE-AUDI-02-00A0.dtbo /lib/firmware
Uncomment in /boot/uboot/uEnv.txt:
optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
Reboot
Load cape.
echo BB-BONE-AUDI-02 > /sys/devices/bone_capemgr*/slots
Then install asound.state
wget https://raw.githubusercontent.com/CircuitCo/BeagleBone-Audio/files/asound.state
mv ./asound.state /var/lib/alsa/asound.state
Then aplay works.
wget http://www.thesoundarchive.com/starwars/forcestrong.wav
aplay forcestrong.wav
Then install pianobar. The version in the Wheezy repos has TLS problems, and the recommended fix is to build from source.
git clone https://github.com/PromyLOPh/pianobar.git
Install a bunch of prereqs. Gmake is GNU make, which is already installed.
apt-get install libgnutls-dev
apt-get install libgnutls26
apt-get install libgcrypt11-dev ligcrypt11
apt-get install gnutls-bin
apt-get install libjson0
apt-get install libavfilter-dev
apt-get install libao-dev
Then make fails with:
root@rascal-pink:~/pianobar# make clean
CLEAN
root@rascal-pink:~/pianobar# make
CC src/main.c
CC src/player.c
src/player.c:40:36: fatal error: libavfilter/buffersink.h: No such file or directory
Unfortunately, the more recent versions of pianobar don't work with libav 0.8, so this is a dead end on Wheezy. See PromyLOPh/pianobar#444 (comment)
On the BBB Jessie 2015-02-15 image, pianobar installs via apt and seems to run well, except that the audio shield may not work because maybe capemgr doesn't exist any more.
Next: trying to get the audio cape working as with Wheezy.
