The solution is to remove the audio drivers again with DDU and follow the realtek installation guide again, patching its dllI'm running a 2010 Mac Pro with OpenCore and UEFI dual-booting macOS and Windows 11 21H2 (22000.652) - so the latest version. I disabled Secure Boot, Driver Signing, and Defender, then followed these instructions, and I was able to get DDL and DTS Interactive showing in Realtek HD Audio Manager and working in games like Overwatch: I could hear discrete sounds from all 5 individual channels, depending on my position. If a gun was firing behind me and to the right, I heard it from the right-rear speaker. As my character rotated, the sound would move from speaker to speaker properly, as expected.
The last time it was working properly was probably around early February.
I fired it up around March 8, and suddenly I only hear sound from the Front-Left and Front-Right speakers.
I test it in Windows Sounds > Playback tab > double-click Realtek Digital Output > Supported Formats tab > under Encoded formats, select Dolby Digital > Test > I hear 6 discrete sounds from 6 discrete separate channels properly (5 + sub). I click the Advanced tab > Default Format is Dolby Digital Live (5.1 Surround) > Test > I hear the same test sound from the Front-Left, a pause (which would presumably be the center channel), then the proper test sound from the Front-Right...and that's it. Every time, I see the "DECODE" light actuated on my Logitech Z906 "receiver." I check the General tab > Jack Information > Rear Panel RCA Jack - which is incorrect. I am connected via optical TosLink cable.
Spatial Sound is off.
FWIW, in the Realtek HD Audio Manager > Speaker Configuration tab > only 2 speakers are showing, and in the Speaker configuration sub-section, Stereo is selected and grayed out/greyed out/disabled. So, it seems the machine isn't detecting the fact that the speakers are connected via TosLink. So, I disconnected and reconnected and even tried a different cable. No changes.
I uninstalled the drivers, tried the latest ones, tried the Windows ones, reinstalled Windows, and tested just about everything else I could imagine.
What the heck could've happened over the last few weeks? Radeon RX580 update? I'm out of ideas.View attachment 245232View attachment 245233View attachment 245235View attachment 245236
Just kidding. I just tried it again, and same problem. Nothing has changed except the fact that I haven't booted to Windows on this machine in about 2 weeks, but I did update macOS to 12.4. So as you previously suggested, I removed the audio drivers again using DDU, making sure to disable both my wifi and ethernet connections while running DDU in Safe Mode, then I followed the Realtek installation guide, patching its DLL, and still I'm having the same issue as previously stated.The solution is to remove the audio drivers again with DDU and follow the realtek installation guide again, patching its dll
try to use versions older than R2.80, such as R2.70Just kidding. I just tried it again, and same problem.

Ok. I’ll try it.try to use versions older than R2.80, such as R2.70
This did not work unfortunately. I still only hear 2.1 sound. It's as if I have the proper drivers that show Dolby Digital Live 5.1 in the sound options, and it is selected, but it's like I don't have the proper license to unlock/utilize DDL 5.1.try to use versions older than R2.80, such as R2.70
I was waiting for your feedback, just create my account to thank you. I'm in the exact same situation.So I just used DDU to wipe out all the old drivers and let Windows take over. Here is what it installs by default:

Notice it says "Rear Panel Optical Jack" and Dolby Digital is available. When I test, I hear sounds from all 6 channels.
But no Dolby Digital 5.1. Only 2 channel:

I also have AMD Radeon Adrenalin software installed. I wonder if this is somehow conflicting. Should I remove it?
Is the below unsigned driver an issue?
