Would you happen to have a link to the DTS Ultra Pack your talking about above?
This is from the thread "DTS:X APO4 + DTS Interactive for Most Devices" in the forum.
I am assuming you are using a Realtek USB based solution and not HDAudio.
Once you have installed, did you go into FX Configurator ?
You don't need a modded one (in fact i use the vendor drivers from Asus).
To enable DTS Interactive over SPDIF for Realtek USB Audio (using the new simpler method) :
- Download and Install the DTS Ultra Pack from the thread "DTS:X APO4 + DTS Interactive for Most Devices".
- Go to the folder "\DTS-X Ultra\SETUP\FX Configurator" and open FX Configurator.
- Locate your SPDIF output from the drop down list (for me it's "[Active] Realtek Digital Output (Realtek USB Audio) {xxxxxx-xxxxx-xxx-xx-xxx-xxx}" and select it.
- It's the xxx-xxx-xxx-xxx ID that you need, and you copy it by clicking "Copy GUID".
- Go to the folder "\DTS-X Ultra\SETUP\HDA" and open the file "Multichannel [Interactive].reg" in NOTEPAD.
- There are two registry keys :
- [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{DEVICE-ID}\FxProperties]
- [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{DEVICE-ID}\Properties]
- Overwrite both of the "{DEVICE-ID}" with the GUID you copied from Step 4 including the parenthesis {curly brackets}.
- Save
- Double click the "Multichannel [Interactive].reg" to apply it to the Registry
- Reboot (it's easier than restarting all the services).
- Go to the Sound Control panel and open the "Realtek Digital Output" and you should be able to select DTS Interactive instead of 2 channel.
- Done
I am working through Ferathers instructions to make this permanent, but my IQ isn't quite as high, so it's taking me some time.
In answer to your other questions :
- I don't play Watchdogs, so I can't answer that. But it does work correctly for me in Forza Horizon 5 (full 5.1), but not in FS2020 as that game appears to be Stereo, so I get DTS Encoded 2.0 output to my Z906. 2 channel / Stereo playback works fine for me in all cases.
- If you are using Realtek Modded Driver, this is not needed for Realtek USB solutions using this method. So if you are using an HDA based driver (versions 6.0.xxxx instead of 6.3.xxxx), you shouldn't be using this method and this thread isn't the right thread for you.
- My config is very vanilla, basic driver, no mods, only DTS Interative enabled using the above.
- When I check the Sound Control Panel, I can see 6 channels are enabled
