Windows 10: Slow motion video / audio playback

A Level 2 Technician just finished installing Version 1809 in to my Dell 5755 laptop, trying to resolve my slow motion video / audio playback. BUT 99.9999% of the time I have no audio at all. This has been ongoing since waaay before the upgrade to the 1809 version.


In settings>systems>sound, there is a slider bar, and a speaker icon with an X (mute) button. Neither will work at all. Above it, the dialog box says "no output devices are found". Says the same thing below the slider bar for the microphone, i.e., "no input devices are found". Both are drop-downs, but neither drops down anything.


I hate to say this, but I am able to get **** to play normally, but nothing else. Trust me, I DON'T GO THERE. I was told by my Brother-in-law to try this particular site, and it worked. THAT'S NOT THE REASON I WANT MY PC TO HAVE IT'S AUDIO AND VIDEO BACK TO NORMAL. I'm a youtube and sports junkie, and haven't been able view either for nearly a year, except on my Android. This PC is a 17" screen. Which would you rather use for viewing videos, or listening to music, or a ball game that's not being televised in your area, but it's on the PC's radio app(s)...except I HAVEN'T BEEN ABLE TO USE ANY application or program that involves video or audio, PERIOD. I just get slow motion audio / video CRAP that only makes me turn the damn thing off.


There is also a red X by the speaker icon in the taskbar, and it won't go away, either. Of course, that's because I don't have sound to begin with.


Troubleshooting ANY AND EVERYTHING does no good, and there have been nearly a dozen Microsoft technicians that have tried to fix it, and now...after a COMPLETE INSTALL from version 1803 to version 1809, by the Level 2 Technician...NO DICE...NADA...NO CHANGE AT ALL. My wife has a near photographic memory, and says that the trouble began on this Dell 5755 laptop of mine, ONLY after the last version 1803 update. She also has told me that she had read online that many, many more PC owners with Windows 10 had experienced the same, or nearly the same problems, which would suggest ( to me ) that this is Microsoft's fault! So, WHY am I having so much trouble getting them to fix it?


I'M READY TO PULL THE FOUR HAIRS I HAVE LEFT ON MY HEAD OUT!!!! Does anyone have any ideas about what avenue I might go down now? BTW, this involves the laptop's internal speaker, as well as any headphones, earbuds, or external ( Bluetooth or wired ) speaker(s).

no sound on slow motion video lumia 950

Hi.

The audio playback feature for videos being played on slow motion is not available on Lumia 950.

We suggest that you put this on the feedback app for consideration on future updates.

Windows 10- video player playback speed slows down

While playing back a video, playback plays good then goes to slow motion.
