Hi Stefan, thank you for your response.

I am aware of that...
I did "snd_bcm2835 enable_hdmi=0" in /etc/modules.
"modinfo snd_bcm2835" shows as below. Doesn't it indicate snd_bcm2835 having
an option enable_hdmi???

It seems that the contention of grabbing HDMI audio output between vc4.ko
and snd_bcm2835.ko can be addressed if snd_bcm2835.ko honors the
option enable_hdmi with its default =0, but currently enable_hdmi seems
having no effect in behavior of snd_bcm2835...
