However, my old AV system cannot do 4K, so I've had to change my computer's HDMI outputs to go directly to the TV (Windows 10, Nvidia GTX 1080Ti). The problem is (and after hours with LG support), they have told me the TV cannot pass-through 5.1 and thus on the computer it would only show as 2.0. This was quite the let down.

I stumbled upon the CRU tool and in the extension block changed it so that 5.1 should be recognised. After restarting Windows, the sound options now give 5.1. But alas, when I try to do a test, I only get sound from the left and right speakers but nothing else. So my question is, am I doing something wrong? Should this be possible? Have I perhaps missed something, or won't the Nvidia drivers work with a custom EDID?

If the TV can't pass through 5.1, how do you expect 5.1 to work? The custom EDID is working or you wouldn't get the option for 5.1. The TV is receiving 5.1 but only passing through 2.0.
