Windows 10: May 2020 update breaks digital audio outputs

After installing May 2020 update my S/PDIF outputs stopped working. No amount of rebooting, removing devices from Device Manager, removing various drivers, updating various drivers, checking cables and so on helped. Audio playback levels are registered by the Mixer, headphone jack or RCA works fine as well, just no sound comes from digital ports. I've got no dedicated soundcard, just integrated stuff on the mb ASUS P6T SE.


After hours or looking through forums that have similar posts about Creators Update in no small amount and different Windows settings, i rolled back to my previous installation update 1909, build 18363.836 and voila - digital audio works again!


I admit, my hardware is rather old, but there's no reason to break stuff that has been working for ages, is it? Now this is an absolute upgrade blocker for me, which was so annoying that i made effort to register on this forum and create this topic.

How to select PCM stereo output for digital audio S/PDIF jack?

I am looking to upgrade the sound from my PC. I wish to bypass the sound card of my computer by plugging in a digital-to-analog converter (DAC) in a USB 2.0 port. I've learned I can stream digital audio that way by selecting my DAC as the default audio output
device. However, the DAC I am considering also can stream data from the digital optical output on my PC to the DAC. A tech rep for the DAC told me to stream music from both the optical output
and the USB port alternatively and see which sounds better. However, for the DAC to utilize the digital optical jack it must be set to pulse-code modulation (PCM) stereo output.

Hence my problem. I see no menu option for selecting PCM stereo output as opposed to DTS or Dolby multi-channel audio in my sound controls for the optical output (in the "Supported Formats" section of the "Digital Audio S/PDIF Properties" menu. (Microsoft
WMA Pro Audio is also offered in that menu, but I don't know what that is or if it changes the digital optical audio output to PCM format.) I would like to utilize the digital optical output from my PC as the DAC rep suggested if at all possible. Please advise.
