Or tell the kernel to completely ignore the ELD (which is what is
checked for audio characteristics, not the EDID).

Add to etc/modprobe.d/whatever.conf the following options:

options snd-hda-codec-hdmi static_hdmi_pcm=1

Having said that... if you hear no audio at all, that won't fix
anything, this only tells alsa drivers to not restrict the output
capabilities.
You need to be able to hear something first, only then can you attempt
to unlock digital passthrough
