Here are the steps I took so far:
(1) Completely cleaned AMD drivers using the DDU tool from 3dGuru
(2) Reinstalled AMD drivers
(3) Set custom resolution with CRU and using the dat file you provided
(4) Set custom resolution with CRU with extension block unchecked and deleted the dat file you provided (will not work with it checked)

The driver doesn't need to be patched with this card but I tried that as well just to see if it would work. I used all of the steps outlined above with the driver patched as well.

Current config:
- Radeon HD 7750
- CRU custom res of 2560x1600@60Hz via HDMI
- Include extension block unchecked
- Latest AMD driver
- Driver NOT patched

I ran the EDID utility and attached the output files.

The EDID doesn't change with the video card. You shouldn't have to do anything differently.

The extension block must be enabled for audio to work. Does audio work at 1920x1080 with the hdmi-audio-5.1-192.dat file? If you run reset-all.exe and reboot, does audio work at 1920x1080? Does audio work with the hdmi-audio.dat file?
