Microphone is not working, How can I fix that ?(Acer Aspire A515-51G)

@brummyfan2 Hi I have one problem and that is my microphone is not working and when I go to record a voice and when I play games can you help me please would be grateful

To add to the above questions - I have the same laptop, setup as suggested in the above, which I agree is the correct settings. I actually have reloaded Win 10 clean installed, de-activated auto Win 10 hardware driver updates in system settings, loaded all the drivers from the Acer downloads page ( used link as given above in a earlier post). I also tried using the microsoft standard  sound driver. Both the nicrosoft and Acer driver works fine with Win 10 Microphone recorder, and I can record and playback. With SKYPE, when using the Acer or the Microsoft driver, only static noise in the background, with my voice extremely soft. I changed the microphone sensitivity and gain settings, it's just not working in sKYPE with the correct device settings in SKYPE. With a external Webcam, all works fine. And with the above complains with this specific Acer notebook, I get the impression that there may be an issue with this specific notebook ? Or a mismatch between Skype and the Acer  microphone ? Any one out there has a similar experience, as I am out of ideas ? Unfortunately I deleted the recovery partition to reload the Acer standard setup, as I normally prefer to use a Win 10 clean install with no extra's.

I had same problem due to Windows Privacy settings I made when setting up the machine for my wife to use.

In recording devices, two devices are listed :- Microphone Array(Default) and stereo mix but does not respond to any sound. I've also tried uninstalling the device from device manager and reinstalling the audio driver from acer website but it doesn't seem to work. Any possible solutions that might fix this ?
Thanks

bro can u tell me how did u solve that microphone problem ? i have same problem with my acer nitro 5.

I had this problem for hours, and here is what solved it for me.  The first time you plug something in, it asks you what device you just plugged in.  I guess I had picked headphones, not headset years ago and clicked "don't ask me again".  I had to uninstall and re-install the audio drivers using windows update.  When I plugged in my headset, it asked me what device is was, and I chose headset.  Problem solved.  Totally ridiculous that these hidden settings can cause so many problems.
