How can I turn off the live feedback of my microphone?

Asked by PeterShinners

Whenever my microphone is plugged in, the computer is echoing the sound like a microphone. I want to be able to record audio, but not hear it played directly to the speakers. This results in a lot of feedback and problems with loud music.

I have a Create Labs sound card using the emu10k1 driver. There are tons of switches in the sound mixer, but none of them seem to turn off the feedback.

In most cases an application has the possibility to switch this off.

But: The best way is always to use headphones instead of speakers. See: No professional sound recorder likes speakers pointing towards a microphone as the microphone of course records all it "hears". Therefore even a switch can only make it better but not totally remove it. Using headphones is the smartest way with best results.

But the microphone is "live" under the normal desktop at boot. This is under gnome, not any specific application.

I see. A microphone gets muted when it is not in use. You should therefore go to the volume settings and mute the microphone or line-in channel.

I get the same thing, the sound of the microphone gets output through the speakers.
So, if I want to get the mic sound for chatting and telephony, I don't think is a good idea to mute it.
And I don't know if this speakers output, will interfere with the sound quality of the service I want to do.
I mean, I remember in windows, when u test the mic, there s a visual output, not through the speakers.

So, If any one has an idea about... it will be use full. And if I find out more... I'll try to impress it down here.

Can you help with this problem?
