--- Comment #1 from cprigent <christophe.prigent at intel.com> ---
Reproduced with following steps:
1. Boot with screen connected, execute command "cat /proc/asound/card*/eld"
2. Execute command: "udevadm monitor"
3. Unplug HDMI cable
4. Plug it again, execute command "cat /proc/asound/card*/eld"

Actual result:

$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[97.764995] change   /devices/pci0000:00/0000:00:02.0/drm/card0 (drm)
UDEV  [97.768234] change   /devices/pci0000:00/0000:00:02.0/drm/card0 (drm)

$ cat /proc/asound/card*/eld*

eld_valid               0
monitor_present         0
