My computer makes an echo sound after I muted the microphone

1- check your mic with an audio amp.
2- Make sure that filter section of Audio Driver of your system has not been changed.If in doubt,uninstall and then reinstall it using mother board CD driver.

Go into sound properties and make sure the microphone properties isn't checkd at "mute".

Hello
Go to control panel sound. Find microphone settings. Click mute microphone then apply.

The echo is from your mic picking up sound then replaying it through your spekers.

if you are referring to a computer with your microphone & headset attached
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it or select audio from the microphone drop down list make sure you have the right one selected and in the volume box make sure the microphone box has a tick in it or select the voice tab and make sure that you have the right media selected also select volume make sure the box for microphone has a tick in it
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it
click start control panel on the left select hardware and sound then select manage audio devices then recording you should see a microphone right click select enable windows 7
hope this helps

Make sure that the phone isn't muted. There should be a button that looks like a microphone. If it's gray then the phone is muted. If it isn't, try using the camera or something to make sure your phone's microphone isn't broken.

im not sure what isn't means

Echo is caused by a number of variables. Are you in a large room with mic extended away from you? Mic too far away will create echo. Also try turning down the gain for the mic

Adding a mike doesn't create echos/feedback. Windows? Version? Right click on speaker icon in lower right and go to recording device mixers, can mute and adjust level of sound sources, also microphone power and pre-amp. Telephones and other devices (laptops) with both input and output will feedback unless the input is "noise cancelling", so you will have to be much more careful with the placement of the external mike compared to using the built in mike.

I hope this can solve your problem. Your computer might have a built in microphone that might be on. Open the Audio Properties and mute the microphone. I didn't think I had a microphone on my computer until I was playing around with a program one day. They can be hidden very well as I still haven't found mine.

However, try that and see if it resolves the problem. If not, at least I eliminated one potential problem. Good luck! :-)

Sounds silly but, try muting your built in microphone, because i'l bet, the mic is picking up the sound from yours speakers and causing the echo. That's wot i've found on a few occassions. Other than that, check sound and video drivers by click Start>Run, then type in 'dxdiag' (without quotes) this will run a diagnostic on audio and video. Please rate this solution
