...and there are no monitors connected to the NVidia GPU. So maybe it is
powered down. Try to disable this by adding this parameter to the kernel
command line:

nouveau.runpm=0

Anyway, this is a kernel bug, not something that can be fixed in PulseAudio.
All we can do here is to gather some evidence.

Please verify (without the above parameter) whether this command also gets
blocked in the kernel. Run it repeatedly just in case.

amixer -c2

Also try:

alsamixer -c2

and mute/unmute various spdifs repeatedly.

Finally:

time pasuspender -- aplay -d 5 -D hdmi:2 -f dat /dev/zero

OTOH the EDID question by Raymond has absolutely no sense, exactly because you
have nothing connected to the NVidia GPU. So, it cannot (and should not) get
any EDID.
