So, let's debug with the pulseaudio log.

Enable the debugging log in the pulsaudio:
edit /usr/lib/systemd/user/pulseaudio.service, comment out the line starting with ExecStart=..., add a new line "ExecStart=/user/bin/pulseaudio -vvvv --log-target=file:/home/your_user_name/pa.log

reboot

Then tail -f ~/pa.log

Plug the hdmi monitor, and select the hdmi audio as output device from UI. now check the pa.log, could you find the "configured_default_sink" from the log, it indicates the change of configured_default_sink.

If the hdmi audio is set to configured_default_sink and keeps unchanged during the suspend and resume, the hdmi audio should be the output device after resume. So please check the changing about configured_default_sink in the pa.log.
