Applicable platforms: STM32MP157-DK1, STM32MP157-DK2.
Audio is enabled in the demo configurations, with some ALSA utilities installed in the root filesystem.
Get started with:
# alsactl restore
This command loads the ALSA setup configuration for the soundcard. You just need to plug you headphones to the Jack connector and play a sound.
# aplay /usr/share/sounds/alsa/Front_Center.wav
