So my audio playback on the laptop was breaking up constantly. So I tried my other laptop, and same thing!
Both are running W10, so I figured a Microsoft broke something in an update. So down the rabbit hole I go:
1. Rebooting didn't fix anything.
2. Drivers were all up to date.
3. Different audio playback proggies all exhibited the same problem!
4. Even Audicity!
As Holmes would say, "Quote: Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.
I decided to look at the main speaker interface -- it's one of those cheap Logitech speaker systems that has a bass-y speaker in the main box and little speakers for the stereo stuff and the bass is so gawdawful that I snipped the wire, I still have to add it the audio pot that I bought to control the volume, but I digress...
And what do I find?
The power plug input to the box is not fully seated in the receptacle!
Push it in properly, and no more breaking up of the audio! I guess certain frequencies of the audio (not very high, mind you) was somehow reverberating into the box just enough to momentarily break the power connection.
Sorry to blame you, Microsoft and W10!

You shouldn't be, Marc. As any good engineer, you first traced the most likely path of failure.

Remove any "Antivirus" suite that was shipped with it. It's likely Mcafee Livesafe. Windows defender will supplant it and it is sufficient for most heathens.

That should be for all the things they did you didn't catch, undocumented features?

My wife's laptop has a dodgy power connector (in the laptop, not the cable). Yesterday she came to use the laptop and it was dead, despite being on charge overnight. She spent 15 minutes wiggling the connector in the laptop power socket, trying to get some power into it. Eventually I offered to have a go, but before doing that I looked at the mains socket. Which was off.

I just got to understand display port is not HDMI. before I took display port for granted as HDMI interface.
today I try to hook my monitor with my DELL T5810 by HDMI cable. but it turns out the interface on the DELL chassis is a display port interface, not HDMI.
so I have to buy another adapter (display port to DVI)to connect it to my monitor.
also I find this link is useful.
diligent hands rule....

And they are not cheap, I found the same problem, 2 display ports do not fit my old HDMI monitor. I will eventually get an HP monitor just to see if there is a difference in resolution.

now I can recognize four interfaces: DVI, VGA,HDMI, and display port plus choice of female or male type.

Is this a useful invention It is intended to aid the unsighted Imagine a 2D array of small audio output devices let's say 100x100 Assume they are small enough to allow such an array to span the width of the face or perhaps even full around the head Further assume a video system permitting 3D information Now convert the visual 3D to audio 3D onto the array I await your more knowledgeable reply - Cheerio

Probably more useful: a diaphragm-device you can place over each ear that reproduces audio signals via electrical voltages. So a production can have an actor say, "The stage is lit by 1000 Christmas tree lights of every color" and the person without sight can vainly try to picture color from that auditory input, instead of vainly trying to picture colors based off the simultaneous input of thousands of speakers emitting sounds around the entire periphery of the head.

May I please request consider the production actor speaking over the diaphragm device placed over each ear powered by electrical voltages may not be able to inform the unsighted as to how to prepare dinner Re/ diaphragm devices I favor the Spendor A7 but lust after the D9.2 - Cheerio

Something to navigate by would seem more desirable (first); where you wouldn't necessarily have to have 2 good ears. Sound / noise / pressure wave forms. Tie in the space-mapping found in AR (headsets).

You are quite correct Our unsighted friend is assumed to have two good ears May I please inquire does AR not require two good eyes - Cheerio

No ... it requires good cameras, for starters.

Happy Holidays My question was in regards so called "spatial mapping" to which you referred I looked the term up on internet to learn it involves visual presentation of 3D information obtained from infrared cameras as per "HoloLens" The critical term here is "visual" which of course is of no use to our unsighted friend - Cheerio

Space-mapping involves mapping the environment the subject travels in. "Visual presentation" is ONE type of "output"; we have MORE than one sense. How do bats navigate in the dark? Where do they get their information from?

Our unsighted friend is not a bat Bats have sophisticated processing skills inherent We do not Any processing can of course be performed off board however the ultimate question remains how to present this 3D information to our human subject I can think of no other than a 2D acoustic array which presents the 3'rd D via acoustic variations to wit i.e. e.g. tone frequency , volume , beep frequency etc. - Cheerio

Processing skills = CPU. That's why it's called "augmented".
AR cameras capture 3D information in digital form. The digital form can reproduced as visual, audio, etc.
The bat was a metaphor; more akin to your solution than you're apparently aware of.

Set it up as a pair of glasses to reflect the viewing area of a sighted person. Feeding into a set of ear plugs. I would assume the brain is wired for forward looking, bi focal vision rather than surround vision.

I doubt humans hear that well.
And such a device would of course rendering hearing other things, like oncoming automobiles, difficult.
