Hi,
I am trying to get the bela card to work on a beaglebone black using debian 8.7 and 9.1 using the BB-BONE-AUDI-02-00A0.dtbo overlay.
I've been unsuccessful in both versions when trying to use the arecord to capture some audio and save it in a wav file.
I've run:
wget http://elinux.org/images/1/10/BB-BONE-AUDI-02-00A0.zip
unzip BB-BONE-AUDI-02-00A0.zip
dtc -O dtb -o BB-BONE-AUDI-02-00A0.dtbo -b 0 -@ BB-BONE-AUDI-02-00A0.dts
mv BB-BONE-AUDI-02-00A0.dtbo /lib/firmwareThen edited my /boot/uEnv.txt file to load the overlay:
/boot/uEnv.txt on debian 8.7:
optargs=capemgr.disable_partno=BB-BONELT-HDMI
cape_enable=bone_capemgr.enable_partno=BB-BONE-AUDI-02 and rebooted the beaglebone and checked that the overlay has loaded successfully which it did.
