Windows 10: Speaker output going to headphone jack, speaker jack output not working

The title pretty much sums it up. I have the output set to Speakers Realtek Audio , and when I plug the speakers into the motherboard in the back of the comptuer I get a popup message asking what device that is. I indicate front speaker, but there's no sound from that jack. When I plug in the headphones with the output still set to Speakers I get no popup but the audio plays through the headphones.

No sound from speaker/headphone output jack with Realtek ALC269

Sometime during the March updates the Windows Update completely broke my laptop system (Acer Aspire 5820TG - 424G50Mn). I ignored it for a long time due to lack of spare time until I saw a few days ago that Redstone 5 was available for download and now I finally have some time to take care of my laptop. I decided to perform a clean install of Insider Preview on my SSD.
But now after the clean install I noticed my audio device isn't working as it should. I get sound out of the laptop speakers, but when I plug in my speaker or headphones in the audio jack, no sound comes out of it. The volume mixer tells me there is audio signal. The jack detection is working as the Realtek Audio Manager warns me (after I enabled it) when something gets plugged in or unplugged. It even correctly mutes the laptop speaker. But the just no actual sound coming out of the speakers/headphones.

It's not a hardware failure in anyway since the laptop and the sound system works PERFECTLY (sound out of laptop speaker, sound out of headphone/speaker when audio jack plugged in) if I boot up in Linux. Microphone jack does function properly in both Windows 10 and Linux.

I tried all kind of drivers, from laptop manufacturer, to Realtek's, to the ones in Windows Update Catalogue. Non of them seem to fix the issue

I tried various drivers:

• 64-bits drivers offered for my laptop model on the Acer website
• Generic 64-bits drivers offered on the Realtek website
• Drivers offered on the Windows Update Catalogue

Non of them helps fixing the issue of no sound coming out of the output jack.
I know 100% that it's not a hardware issue since my Linux install are working fine. So that makes me believe it's either a driver issue (quite some people seem to have this problem as well with Realtek) or a Windows issue.

I really need some help to resolve this...

 

Headphones into rear audio jack?

Headphone output jack has a headphone amplifier.

Speaker output jack doesn't have a headphone amplifier.

 

Speaker output not working after windows 10 update

My speaker output no longer works after the windows update, the headphone jack is working but not the output in the back of the desktop, anyone have already found the solution? I saw another post where the issue is backwards, headphones is not working
but speakers are.
