Applications -> System Tools -> Nvidia Xserver Settings
GPU 0 -> <display> [Acquire EDID]

Now I re-apply this captured EDID via "Option customEDID"

So you haven't actually used a hex editor to modify the correct values
to disable the hdmi audio from turning off on the TV? I have a Samsung
TV also and would be interested in your EDID once you get it working.

Thanks

Just a hint: instead of editing a custom EDID, you can directly apply
the (known) timing settings with the following procedure:

1. Add the timings to the "Monitor" section (using "ModeLine",
"HorizSync" and "VertRefresh"), i.e.:

Code:
Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "SomeVendor"
    ModelName      "SomeModel"
    ModeLine       "5040x1050" 328.80 5040 5104 5168 5376 1050 1053 1057 1073 +HSync +VSync
    HorizSync      31-80
    VertRefresh    56-76
EndSection
2. Tell the nvidia driver to ignore the EDID of the LCD and instruct to
use the timings as given in the "Monitor" section (use the options
"UseEDID" and "ExactModeTimingsDVI" in the "Screen" section):

Code:
Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "UseEDID" "False"
    Option         "ExactModeTimingsDVI"      "True"
    [...]

Hint #2: you can easily calculate a specific modeline using "gtf".
I.e. "gtf 800 600 70" would calculate the modeline for 800x600@70Hz:

Code:
  # 800x600 @ 70.00 Hz (GTF) hsync: 43.75 kHz; pclk: 45.50 MHz
  Modeline "800x600_70.00"  45.50  800 840 920 1040  600 601 604 625  -HSync +Vsync

Hint #3: if you don't know the timing settings but the display is working
properly on a windows computer, then you can use either "powerstrip"
or the nvidia configuration tool to retrieve the currently active video timings.

hope that helps!

regards

Bernhard

I captured the EDID file and edited in the xorg.conf but it won't sleep!

What model do you have? I wrote a custom EDID for my 1080P Samsung to turn off HDMI audio. I can PM it to you, but it could blow up your TV

I did the edid.bin tweak, even if 126 was already at zero I even tried changing 127 bit but I still have the black screen.
Now I'll try latest stable 180.25

I stumbled on this thread and I thought of mentioning that someone did a nice program to strip the audio block from a captured edid file:
