sudo su to gain root access.cd /boot/dtb/rockchip to navigate to the rockchip directory.mv rk3588s-9tripod-x3588s.dtb rk3588s-9tripod-x3588s.dtb.bak.reboot to reboot your device.Issue reported on ameriDroid's Discord server (click the link to go to the Discord post):

and
&spdif_tx2 { status = "okay"; };[...]
