<pre>My TV Pioneer pdp 434 seems to have an broken EDID (CRC error). It is connected
via an Onkyo AVR.
The System (ASROCK n3150m) is not enabling HDMI when TV is on and/or is
connected directly. HDMI is enabled when the AVR is on and TV off.
This issue is handled with drm_kms_kernel_helper edid overridings. But HDMI
sound is not working when TV is on. /proc/asound/card0/eld* is not populated
although drm is detecting 8 SAD in the valid edid file which i have given.
Currently i am attaching an udev rule to drm events which is disabling and
enabling audio via xrandr when /proc/asound/card0/eld* is not populated. The
rule is executed when i am switching tv off. After switching TV on i have got
sound until the system is not executing any xrandr command.
Distribution is OpenElec by fritsch with 4.3 Kernel. I was redirected to here
from <a href="http://forum.kodi.tv/showthread.php?tid=231955&pid=2148990#pid2148990">http://forum.kodi.tv/showthread.php?tid=231955&pid=2148990#pid2148990</a>

I am not sure if it is the same issue: /proc/asound/card0/eld* is also not
populated with given edid file without any connected HDMI.
