Posted by Anonymous on
You can reinstall the sound drivers from the Acer recovery management, to do so:
Start Menu> All Programs> Acer erecovery management> Restore> Restore Application & Drivers> Contents> Select Realtek and install it
Got to http://gd.panam.acer.com/home/
Select the computer model
Select Operating System installed on your computer
Select Audio (Realtek) and download it.
Once downloaded, install it on your computer.
Thanks and regards,

Try plugging in an external microphone. If it works, then your internal microphone has failed. If the external microphone also doesn't work, then try reloading the Realtek Audio Driver. There is also the possibility if you have previously used an external microphone, that the jack's connections have become unreliable such that the system thinks that an external microphone is still connected after it has been unplugged. With this situation, plugging an external microphone back in will obviously work.
