Problem: Internal Mic doesn not work at all. I am unable to setup google assist or do anything anything that requires the mic.    
I have been doing troubleshooting: 
checked my mic is not muted 
checked chrome settings its set to ask 
turned off bluetooth, although i like it on since i am using bluetooth to connect my phone/mouse 
changed channel to beta didnt help
made sure ChromeOS is up to date
check both device and google account settings mic is on
google assistant is on
logged out
restarted device
plugged in headphones just to see the volume settings for mic, didnt help 
external mic or headphones not connected
sound works, I can hear just fine in all apps with built in speakers.
I have the same google account on my phone and the google assist works fine.  

I purchased the Acer Chromebook R11 C738t series, April 2020. I am a new chromebook user. Am I just missing something or is this device broken. I read in another post adding external mic may still did not work. I really don't want to have to go through returning and finding a new chromebook. 

Anyone else having this issue and was solved without just getting a different device?

Update: I received help from Acer on social media. They directed me to a tool call mictests.com I was able to run the test and the site was able to fix the problem. The mic works now.
