Very weird problem. I purchased two cheap laptops of the same make and model, that I installed Windows 10 Pro from the Windows 10 Educational that they came with.
The first computer had no problems and everything worked as expected.
However, when I, using the same disk, installed it on the second computer, the microphone, speakers and speaker port were all reported as not being connected.
Yes, I followed all of MS’s hints, ran Troubleshooter,and followed a number of hints found on the web.
FWIW and to save on replies, I used the same disk simply so I didn’t have to open the second one and YES I did use the second license.
I did some checking and found that the serial numbers are only 5 units apart, the BIOS version and motherboards are the same, and I also checked every setting in the BIOS and all choices were identical.
Device.mgt showed that the drivers were install and reported OK.
And, again yes, I completely wiped the drive and reinstalled Windows and got the same results. I even trued the second disk, but again got the same results.
What’s odd is when I installed Arch Linux, it had no problems recognizing the hardware.
And again, the speakers, microphone and speaker port were all working fine prior to my tampering.
Any other possibilities, I may have overlooked?
