The UCM configuration might not have entries for HDMI. If so, then HDMI
won't be available if PulseAudio successfully loads the UCM
configuration.

If you don't need UCM, you can disable it and use PulseAudio's "normal"
configuration instead, which should make HDMI work (if it worked with an
older version PulseAudio).

Sorry, I lied. You can't disable UCM, at least if you're relying on
module-udev-detect. I'll make a patch that fixes this.
