Issue: No audio from NVidia GeForce GTX 260 DVI output to HDMI input on LG TV

The desktop computer is configured as follows:
Gigabyte P55A-UD4P Motherboard (no on-board graphics)
Intel Core i7 CPU 860@2.80GZ w/ 8GB RAM
NVidea GeForce GTX 260 896MB RAM w/ latest NVidea driver 342.01 (2-DVI outputs)
Windows 10 Pro 64-bit w/ all updates

The TV is an LG 55" 4K OLED55BXPUA

They are connected with the following cable: DVI-D to HDMI 24+1 Bi-Directional 1080p Adapter Cable

A kind person on AVForums helped me resolve my initial problem of no video per this thread via CRU, but we were unable to get the audio working from the computer to the TV and he suggested I seek assistance on this forum.

The audio is configured in CRU as follows there were no audio entries for stereo PCM:
CRU main screen go to extension blocks:
CTA-861 (add)
Data Blocks
Audio Formats (add)
LPCM
2 channel
sample rates 32/44/48
bit-depths 16/20/24
Speaker Setup (add)
* Front Left/Right

If I go to the NVidea Control Panel, it looks like the driver is seeing the LG TV...
   

But when I open Windows Sound Settings I only see the spdif optical and headphone outputs available...
   

I'm stuck at this point and don't know whether there's a conflict between my CRU definitions and NVidea Control Panel. Any advice would be appreciated...8-)

I figured it out, actually. I got really confused about active vs display resolution, and my monitor is an older 1366x768

You need an HDMI data block for audio to work, but you shouldn't have to add any of these data blocks because the TV already defines them by default. Adding a standard resolution isn't the correct solution either, and you shouldn't have to add 1080p because the TV already defines that by default. What did CRU show by default?

Here are the steps I took:

1. Delete current extension blocks, Add in Display 2.0 or 1.3 (Ended up only doing 1.3 since when I reset on 2.0 the montior went black.) Then Press ok/restart driver

2. On new block(display 1.3), I created new detailed resolutions at 360hz 1080p(native) and 1680x1050 360hz and i tried using automatic(PC), Exact, Exact Reduced. Then Press ok/restart driver

3. Went to the Detailed Resolution section, tried to create 360hz with both 1080p native and 1680x1050 using all timing settings, got red text every time.

Note: I tried some other random stuff along those lines, just cant remember. These are just the ones that I think shouldve worked based on what I read in the thread. Sorry if this has already been gone over, but I couldn't find it.

Edit: I saw you had asked someone if you could run some tests with a two extension block monitor, I'd be willing to help you do this if you still need it as long as there is like no risk of anything super harmful happening lol. My discord is Matt22#8058 , id be happy to help if it can help you create this compadibility

#2 says you added the resolutions, so what's #3 for?

Already have the information for that. It's an NVIDIA driver bug with no possible workaround.

CRU shows 1920x1080 (16:9) @ 60 Hz by default in the Standard Resolutions section. I did a reset-all and then a restart64 and the video is still working. So I must have initially recreated what was already present (I'm new to CRU). But with the CRU default values applied I still don't have any audio, and I can't see the TV in the windows sound settings. FYI I have the HDMI Input Audio Format on the OLED set to PCM (not Bitstream). Here is a screenshot of what I see in CRU regarding the audio...

Okay, I didn't realize that adding a resolution into the extension block meant that it would show up in the control panels. I assumed I had to redo it because it didn't show up in the Detailed Resolutions sections after I had added it. Knowing that I tested multiple resolutions on 360hz using Automatic(PC), Exact, Exact Reduced, and a couple of others that I didn't really expect to work. The main two ones I tested were 1680x1050 and 1728x1080 when the former didn't work. That being said, every single test resulted in failure with the monitor just showing that it was going into sleep mode. I saw somewhere that G-SYnc monitors usually can't preform out of some set of presets, so I guess i'd have to find a resolution thats already in one of those?

Note: Found some dude on the Latency and gaming discord who got this monitor overclocked to 434hz with these settings. Don't know if this is useful information or not but just wanted to point that out.

Do you think there's any way to get the audio working with my current setup, or do I need to start looking for an HDMI graphics card? I didn't really have that in the budget for right now! Thanks in advance for any advice...8-)

Your card doesn't seem to support HDMI audio through the DVI port, so you would need to get another card with HDMI, or you can output audio separately using the line out on your sound card or motherboard.
