I attached a work-in-progress patch that fixes the issue with at least one setup using Club3D CAC-2505 DP-alt HDMI converter to the bug at: https://gitlab.freedesktop.org/drm/xe/kernel/-/work_items/8412#note_3543741 Needs more work still, but if this approach works, I'll send a proper patch later to the list.
