How do i turn off my microphone for the acer aspire 5920 series
The short answer is you probably don't, unless your laptop has a BIOS setting for it, which is unlikely.
I had a major privacy conflict with IBM/ Lenovo over that, bur there may be a work around:
1) Using the windows and/or audio card mixer program, e.g. windows volume control, find the microphone slide control and set it to minimum. Also enable the microphone mute button if there is one.
This is not 100%, but it will help, keeping in mind that rogue software can access and over-ride this setting at will.
2) Next, see if you're laptop has an external microphone jack. If it does, plug a short-circuited microphone plug into it. Make sure that the plug's short circuit wire is well soldered for best results. This should disable the internal microphone, and replace it with a dud. Be careful you don't stress and break the jack when handling the PC.
This will be quite effective, but again not a 100%, due to the huge dynamic range of modern audio cards and their ability to recover incredibly weak signals. A 16 bit audio card has a dynamic range of 96 decibels. a 24 bit card= 144 decibels. A 32 bit = 182 db. 1 bit = 6 decibels.
A shorted mic input may offer 100dB attenuation + another 48 db or so from the software volume/mixer control.
3) Finally you may try to totally uninstall the audio driver from windows, or to disable the audio card from BIOS. This will work, but you won't be able to play music either.
4) Another possibility is to physically destroy the internal mike,
look for a pinhole somewhere near your keyboard or display. Plug it up with glue. (Again a partial solution only)
5) There is a real security and privacy issue with laptops, because rogue programs (malware and trojans) can access the internal camera and microphone to spy on you over the internet,
broadband or wi-fi.
