I've got an Acer Swift 3 8th gen i-7 with a 1TB SSD added from Crucial and 24GB RAM also from Crucial I don't want to lose. Their support is useless,
I've tried every Windows t/s option, uninstalled/reinstalled h/w, drivers. Device Manager lists it as Microphone Array (Intel Smart Sound Technology (Intel SST)) It worked lastt year, and hasn't worked in a Web-Ex meeting, or even with Cortana or Google search.
I've tried everything this guy listed in a forum:
My laptop is running on Windows 10 version 1903. I installed this version last week and I am sure this issue comes after 1903 is installed, previously version 1803 & 1809 I have no such problem at all. It stays undetected until today I was trying to communicate with my gaming friends on Discord and found out my mic isn't working properly. After further investigation I realize something is wrong with the system configuration (software issue), the mic issue is not solely on Discord. I googled for almost an hour, literally went through 10+ articles (90% of their methods are similar) and tried out every single possible fix. Finally ended up none of them works. Someone please save me, I am so lost right now.
What I have tried:
I keep testing the mic in this window after every method tested and none of the fix above helps, the bar doesn't responding in green as supposed. I have LITERALLY no idea what is bugging the mic from working properly. This issue is way harder to fix than no sound issue, which previously fixed by myself for a few times.
I have the lastest driver installed: 3/18/2019, 10.0.18362.1
As I said, Acer is responsible for support of your laptop. They made the laptop, they are the integrator, and your warranty and support must come from them. If the unit is faulty, you must work with Acer to correct it, or replace it.
The forum you posted in is for Intel desktop boards, not for acer laptops.
