snd_bcm2835.enable_hdmi=1 relates to the legacy audio driver. As you're loading vc4-kms-v3d that won't be enabled - HDMI audio and video are inherently connected (audio goes in the video blanking periods)
You can confirm for yourself with "aplay -l" to list the audio devices on the system.

Hmmh.

I thought the legacy driver would be turned off with:

Code:

dtparam=audio=off

in config.txt. Which btw still produces the confusing /proc/cmdline entry.
...

If you want to satisfy yourself that the legacy audio drivers are not running, then look at the output of aplay -l (lowercase L), as suggested. But as 6by9 says, there is no legacy audio driver on Pi 5, so it is therefore impossible for it to be active.

A parameter present on the kernel command line do not always have an effect; although they usually do, this is one of those cases where it doesn't.
