Hi, I have a BBB wireless with the lastest IoT Debian image. When I don't have an HDMI screen connected to my board I can take a sound output via i2s on the pins P9.28, P9.29, and P9.31, and ALSA lists a sound device:
[ 2.913839] ALSA device list: [ 2.916851] #0: TI BeagleBone Black When I connect my LCD cape to the board the sound device disappears, even when I disable the cape on uEnv.txt with: disable_uboot_overlay_addr0=1 I would like to know how can I force enable an i2s audio output with my LCD screen attached. Originally my cape uses the pins P9.28, P9.29, and P9.31 ( BB-CAPE-DISP-CT4-00A0.dts <https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-CAPE-DISP-CT4-00A0.dts>) to control the touch and the backlight, but I slightly modified the dts to not use these pins. But even with the cape completely disabled in the uEnv.txt I don't have sound. Am I disabling it correctly? How to force enable audio out?
