BROADWELL I5 NUC - OPENELEC - EDID ISSUE?
#1
Hello Kodi fans and experts!

I currently have a setup where my Broadwell based i5 NUC (latest BIOS installed) is connected to a 5 port HDMI switch. From the switch, the HDMI heads over to a Panasonic Soundbar for pass-through on to my Panasonic TV. When the NUC is directly connected from the HDMI switch to the TV, everything works perfectly. It's just when the Soundbar is introduced that issues arise

When using the latest stable OpenELEC release, the TV loses it's signal right after the NUC's BIOS posts. To remedy the issue, I will disconnect the HDMI from the TV in real-time, plug in the HDMI coming from the switch and whala!, the TV picks up the 1080p signal. After the signal is back, I will disconnect the HDMI from the TV and plug it back into the HDMI In of the Soundbar and the re-plugin the HDMI from the Soundbar HDMI Out to the TV.... and the the signal continues to work....interesting.

Clearly the Soundbar is the culprit in the loop. I've tried a couple of things:

I've explicitly followed the direction on the Wiki for Intel:

wiki.openelec.tv/index.php/Configuring_a_Custom_xorg.conf#tab=Intel

For the xorg.conf - the only thing I changed was 'monitor' and 'identifier'...changed to HDMI1 instead of HDMI2.

For the custom EDID, I used softMCCS to capture the TV's EDID.bin and store it in the appropriate place listed in the wiki.

Everything in place, no luck.

Is there something I might be missing....maybe I need the EDID of the Soundbar instead?

Strangely enough, I decided to upgrade to the latest beta build of OpenELEC (Isengard RC2) and sometimes the signal comes through. I'd say like 40% of the time cold boot....if I reboot, there's like a 25% chance the signal come through. Other times the image will go through, but flicker, display 480p, change from 59.94 to 60.00 out of nowhere....it's strange. But most of the time, the TV reports no signal.

I'll update with a xrandr report when the signal is not working, but basically it will say something like reporting at 1024x768 resolution (assuming this is an unsupported resolution and why the TV shows no signal) but in addition it will say HDMI1 disconnected.

Any help would be greatly appreciated. Thanks!

working and non working, please.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Two separate reboots where the image comes through (this is without any xorg.conf, edid.bin/autostart.sh applied):

&

------------------------------------------------------------------------------------------

Reboot, no image (still without xorg.conf, edid.bin/autostart.sh applied)

after the above no image, I SSH'd "reboot", and the image came back....resulting in this:

Now applying the recommendations from http://wiki.openelec.tv/index.php/Config...#tab=Intel

Cold boot, with all recs applied (xorg.conf, edid.bin, autostart.sh), no image:

seems like it's worse with applying the wiki settings

Rebooted, this one is interesting, all wiki settings applied:

came back with this:

That's for sure a hw failure. It does not think that anything at all is connected. If you use a switch or something get that out of the chain, change cables whatever.

This was more promissing:

As the only thing missing here was to enable a mode, in your case:
Code:
xrandr --output HDMI1 --mode 0xfe

which you could have done via ssh.

So basically the machine does not even recognize that a single monitor is attached at all. This needs fixing first. Remove everything between NUC and TV. In 99.9% the cases this is caused by:
a) Unpowered AVR which does not transmit EDID
workaround: Make sure verything is powered on before you start
b) HDMI switch: There are so many broken device out there

Concerning the workarounds: Make tripe sure that you are really writing the correct EDID into the correct Head.
