Need help with HDMI signale (amp+tv)
Hi,
I'm actually using Ubuntu 14.04 on my HTPC.
Sadly, I've got a problem which I'm not able to fix by myself.
My HTPC is connected to my AMP (Denon AVR-1912). My TV (Samsung Smart TV) is also connected to the AMP.
When I turn on everything with my remote, everything works fine (all at the same time).
If I add a timer for my PVR in the future, the HTPC turns on by RTC and record the timer.
Now to my problem:
If a record is running and just the HTPC is running and I turn on my AMP and the TV, I don't get a picture.
It seems, that the AMP/HTPC handshake (concerning the resolution) is not working.
As desktop I'm using lightdm for Kodi.
Could please someone help me? I also tried a solution with udevadm monitor, which was not working.
In addition I also tried a grub parameter with EDID, which is also not working:
/sys/class/drm/card0
cat: /sys/class/drm/card0/enabled: No such file or directory
/sys/class/drm/card0-HDMI-A-1
disabled
/sys/class/drm/card0-HDMI-A-2
enabled
/sys/class/drm/card0-VGA-1
disabled
root@xbmc:~# sudo mkdir -p /lib/firmware/edid
root@xbmc:~# sudo cp /sys/class/drm/card0-HDMI-A-2/edid /lib/firmware/edid/edid.bin
root@xbmc:~# grep edid /etc/default/grub
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 acpi_enforce_resources=lax drm_kms_helper.edid_firmware=HDMI-A-2:edid/edid.bin video=HDMI-A-2:e"
root@xbmc:~# update-grub
Might this is helping. This is the output from udevadm monitor when the AMP turns on:
root@kodi:~# udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

I would really appreciate if someone could finally help me to solve this problem.
Thanks in advance.
