No sound via HDMI after resume from suspend: ELD info empty

Since updating to kernel 6.15, I no longer get sound via HDMI after resuming from suspend. The HDMI output shows as disconnected in pavucontrol. If I manually reselect the HDMI output device, the sound starts working again. This issue does not occur on linux-lts (6.12.31), where HDMI audio resumes normally.

My GPU is AMD RX 6600, using PipeWire with WirePlumber.

Here’s an excerpt from the WirePlumber log after resume:
