On the machine:

cd /lib/modules/5.0.0-1033-oem-osp1/kernel/sound/soc/sof

mv sof-pci-dev.ko sof-pci-dev.ko-bak

sudo reboot

after booting up, please check nv hdmi, it is initialized successfully (check /proc/asound/cards)

Then cd /lib/modules/5.0.0-1033-oem-osp1/kernel/sound/soc/sof

mv sof-pci-dev.ko-bak sof-pci-dev.ko

sudo modprobe sof-pci-dev

check dmesg, you will find the sof driver fails to initialize:
