(This happens on boot on re-icl-u. After this, `sudo aplay -L` doesn't show any HDMI/DP audio devices.)
Please do confirm bugs on the current upstream drm-tip before reporting upstream.
The dmesg also required drm.debug=0x2 to get the right information here.
Simon, can you attach the dmesg with drm.debug=0x2 parameter?
Cannot reproduce anymore.
