No Sound via HDMI on Newest Stable KDE Neon

Hello, I have no idea how to sort out my sound issue. Older KDE Neon worked out of the box with HDMI. Now, however, with the newest upgrade to KDE Neon the HDMI has no sound when it is set to that output (it’s the only connection).

journalctl -b0 | grep -E "snd|hdmi" | sed 's/^/ /'

The sed makes it format correctly when copy-pasted here with a blank line above it.
