Windows 10: Output device "Digital Audio S/PDIF" not playing sound out loud

My problem is in the title. For more information:
I put Windows on an older iMac and therefore this computer has iMac hardware. This version of Windows isn't activated yet.

When I click the Volume button (and toy with the Volume %) the device shows audio playing, however, I can't hear it out loud.


I know that the sound hardware on this computer does work, because whenever I boot it up, it plays the typical Mac boot-up sound.


I attempted to uninstall the sound drive and restart, to which it reinstalled and still had the same issue.

Troubleshooting says to disable all enhancements, which I have done, and the problem still persists.

I've also tried to simply update the computer, but this has also proven to not fix the issue.


Another small thing I noticed is that when I attempt to plug in earbuds to the headphone jack, it doesn't recognize anything plugged to the jack.


Any responses/help would be much appreciated!

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.

 

Windows 10 S/PDIF sound output not working properly

My Windows 10 S/PDIF 2-channel PCM output not working(e.g. no sound when playing WMA audio and MP3 on media player and watching Youtube thru browser), but DTS, AC3 output is ok.

Anyone got the same problem like this? I use Creative Sound Blaster X-Fi PCI sound card for coaxial S/PDIF output. And have checked system default output is the S/PDIF port which on Creative Sound Blaster X-Fi PCI sound card.
