Hello Ferather,
First of all, thanks for all your hard work.
I've tried your solution on my motherboard internal realtek soundchip over optical and it worked just fine. Problem is, I'd need to keep changing cables as all my devices are connected to the TV over HDMI and then to the Home Theater over spdif.
So, it brings me to this. My PC is also connected to my TV over HDMI (nVidia 3080 card) and I'm able to get Dolby audio from it using (buying) Dolby Atmos. But I really... really want DTS. I even went as far as buying DTS:X and everything looked fine from a software side, but no audio can be heard from my Home Theater though the DTS light does show up when playing something on the PC. (i.e. a Youtube video) and lights off when I stop it.
Btw, this is how it looks:

(as you can see, it's now trying to use DTS:X, but no audio... haven't tried to use DTS Ultra over HDMI without asking first as I don't want to mess with it much more)
After researching a bit, I've read LG OLed B9 doesn't support DTS as LG didn't license it so I just gave up. However... today I plugged my PS5 to my TV and I've noticed it DOES output DTS audio to my Home Theater... so right now I'm lost. If my TV didn't support DTS then PS5 wouldn't output DTS sound either, right?
I'd appreciate your comments. Btw, I'm all in for TeamViewer, AnyDesk of whatever you'd suggest.
Thanks in advance!
