Torizon Core loads wrong sound driver for Dahlia

For everyone else who wants to know the super-secret-not-really-documented handshake for getting sound out of their Dahlia carrier board after installing via EasyInstaller ssh into your board sudo fw_setenv board 'dahlia-imx8mp' sudo fw_setenv board_name 'dahlia-imx8mp' sudo fw_setenv fdt_board 'dahlia' sudo fw_setenv fdtfile 'imx8mp-verdin-wifi-dahlia.dtb' sudo reboot now

Best regards,
