Since you did not specify your kernel version, it is hard to respond. However, assuming you are using V3.8.13, do the following: Make sure the compiled BB-BONE-AUDI-02-00A0.dtbo file is installed under the /firmware folder > export SLOTS=/sys/devices/bone_capemgr.*/slots echo BB-BONE-AUDI-02 > $SLOTS If you want to enable the Audio DT permanently, add it to your uEnv.txt file.
