Ok so I got multichannel PCM to DTS working natively, I get all channels when playing for example 6 channel AAC or 6 channel Wave. I modded the driver to install on top of the current AAF driver.
I was using the "Both decoders" option (don't think it matters), and no additional software (again, don't think it matters), just base drivers and ASIO.

If you have E-APO installed, go to it's installation folder (C:\Program Files\EqualizerAPO\) and delete any .reg files. If you don't have any .reg files skip this step.
You will need to disable driver signature enforcement, see here for a guide, since the files are modded and I have not signed them.
Open "Device Manager", then right click "AAF DCH Optimus Sound", and select "Update driver", then "Browse".

Now select "Let me pick" then select "Have Disk", and navigate to where you extracted the .zip file. Use HDXRT.inf, and for Intel use HDXRTSST.inf.

Ignore the warning about the unsigned driver, and continue with the install, once done, wait a few seconds then restart your pc.

Optional: To get the digital decoder (DTS) to permanently stay on, you will need to enable "Stereo Mix" (I renamed it), mute it, enable listen, and playback to digital.

If you are using E-APO you can now set it up using the configurator, select "SFX/MFX" and "Post-mix" no "Pre-Mix".
