Windows 10: Digital Audio Output S/PDIF failure after windows update

Since the latest Windows 10 update my Digital Audio Output S/PDIF is not producing any sound.When I test the output it shows the device in place and reports it as working correctly. I can see the audio output going up and down on the device but no sound is coming through.My Windows OS details areEdition Windows 10 Pro Version 20H2 Installed on ‎19/‎07/‎2021 OS build 19042.1110 Experience Windows Feature Experience Pack 120.2212.3530.0

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.

 

What could be wrong with SPDIF output?

I have a computer where the S/PDIF audio output has been working for years.

I introduced an SSD into the system to help speed it up.

Of course that meant a different copy of Windows was in place, but also suddenly my sound output to my audio system stopped working.

The driver is the Digital Audio (S/PDIF) (High Definition Audio Device) which provides a facility to test audio output. When I run the tests I hear the audio tones from my S/PDIF audio output on my sound system.

Sound settings tell me that my sound output device is the Digital Audio (S/PDIF) (High Definition Audio Device).

When I try to play any audio from the computer I am greeted by dead silence.

The tests would suggest that there is nothing wrong with my S/PDIF driver, but I don't understand why I am not getting any sound when playing an audio file.

""

• Some audio drivers have an “encoding Audio Processing Object” feature; this is commonly known as “Dolby Digital Live” or “DTS Connect”. This takes the output of the Windows audio engine mix, encodes it (as Dolby Digital, DTS, or some other format) and sends it out over a S/PDIF optical link for decoding by an external audio receiver. An issue was introduced which resulted in this feature no longer working, which is now fixed.
