I'm trying to get my new microphone working and I've been unable to get any output when recorded.

arecord & gnome sound recorder

Do either of those know which device to use? You can get a list of devices with:
arecord -l
Offline
Did you try increasing the Mic Boost? Sometimes a microphone might not be sensitive enough to reception.

I tried increasing the Mic boost in the recording section of alsamixer, I was still unable to record any sound I also recorded from every input Gnome sound recorder supports: "Fronts Mic Boost' 'Mic Boost' 'IEC958' 'Capture' 'Capture 1' 'Digital'
Offline
Would the recording section or the playback section effect the output?

analog or usb?

It's a analog headset, The speakers on it work fine.

What information should I provide? I also wasn't able to get the microphone working on my arch laptop.

in alsamixer, you need to enable the capture on your microphones. have you done that ?
use the arrow keys to highlight the microphone bar. then press space bar to activate it. This should show the word "Capture" in red just below the bar. That will enable the microphone. You can then adjust the Mic Boost accordingly to make sure that your mic doesn't shrill and the sensitivity is not too high.

There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

Here's a screen shot of the alsamixer recording section: http://imgur.com/Z9Rza

Hmm, have you tried upping the Front mic and the Mic Boost? also enable both capture bars.

Yes I have.

This is just a shot in the dark here, but I was not able to get my microphone working until I unchecked Smart 5.1 under "Switches" in the Alsa mixer. My sound card is the HDA ATI SB. If you have that option, try unchecking it and see what happens.
Hope that helps,
Jeff

I could find any option labelled "Smart 5.1" or anything similar.

Can you confirm the mic even works? Do you have a friend with a Windows machine you could test it out on so that you know if it is even operational?
Offline
Is there by any chance that the microphone is disabled through the bios? Have you checked and enabled any audio or microphone option?

I booted into a Ubuntu live session and the mic worked perfectly there, I noted down the details within alsamixer under the Ubuntu system, so I could re-implement them in my arch system. When I booted in arch I fiddled with the input source, setting one of them (the first) as "Front Mic", which I had already done early. It's currently working fine and I managed to get it working on my laptop also (Which was easy consider I only tried it once and that was before I knew you needed to activate the capture with space bar) Thanks for all your help! (Truly thank you!)

Glad to know its working. Please mark the thread as solved.
