Custom Resolution Utility (CRU)

So I used CRU to create custom resolutions with the correct timings, but the moment I do that and restart, my audio is killed (only getting 2.0 on desktop and bitstreaming doesn't work). Would you expect this to happen, or am I doing something completely wrong?

Do you happen to have four detailed resolutions defined? I just remembered an issue with NVIDIA's driver where audio wouldn't work properly if you have four detailed resolutions.

Also keep in mind that the audio is transmitted during the blanking periods, so reducing the blanking will reduce the amount of data that can be transmitted, which might prevent certain audio formats from working.

I'm also trying to figure out what you're trying to do. The original problem seems like a signal quality issue or an issue with the receiver not handling higher pixel clocks, not an issue with incorrect timing parameters. The receiver doesn't change the timing parameters according to your EDID dumps, so what timing parameters are you using to fix the problem?

You also won't be able to separate 23/24 Hz and 29/30 Hz with CRU. I would advise importing the hdmi-bitstream.dat file to wipe out all the resolutions in the extension block. Then you can try adding 23/24 Hz and 29/30 Hz separately using the NVIDIA control panel.
