No Audio output!

AbhinavK

My Acer nitro 5 has got mute. Cross sign over speaker symbol. Shows " no speakers or headphones are plugged in". trouble shooting didn't worked, online video help didn't worked. Sound panel shows no output device present.
Device manager does not shows realtek audio 
Installed many drivers but none of them worked.
 Please help to fix the audio issue. 
The problem arise after there was blue screen with error code QR on the screen. After that audio went.

Sometimes a simple system restore will fix the issue.. 

Try windows x

click on power shell admin or command prompt admin 
type rstrui
chose an earlier date on which your computer was working fine  
click on next, finish, yes
It will restore your computer to an earlier date 
if you get an message - system restore not completed - click on close 
It will show you all the icons..

Try and check whether it is working now ..

It it is still not working you can ..

Go to support.acer.com 
chose your country 
type snid or chose your model 
go to drivers  - Install the sound driver and check.

You  can always  do a refresh and reset.   These are steps to do the refresh and reset .. 


click on start - settings - update and security - recovery - reset this pc - get started 

or 

on start - type here to search - type reset this pc - click on reset this pc on the top  - click on get started 

It will show you keep my files and remove every thing


chose keep my files 
chose the account - type the password - click on local reinstall - click on reset

login to computer and start using the computer. 

If it is still not working 

click on start - settings - update and security - recovery - reset this pc - get started

If you do refresh ( keep my files ) -  all your personal files like pictures, music , documents , videos  will still be intact.   Only the applications will be lost 

 

If you do reset  ( remove everything )  - you are doing a factory default.   It will become like a day one computer.    It will wipe out everything and take your computer to day one like a new computer.
