I have installed 11.04 Ubuntu. I can play music i can listen. But i cant use the microphone input, i tried with alsamixer + pavucontrol+(arecord -d 10 /tmp/test.wav), pavumeter (apt-get install pavumeter), also tried with all related settings. But microphone audio does not get captured.

What can be the issue, it was a new PC just installed Ubuntu 11.04

*** Note:

laurent advised, i see a noise in equalizer as following: (but real microphone is not getting captured)**

To test the microphone, you can plug the speaker in the mic input, maximize the input volume and see if you get something with audio preferences on the input tab (input level bar). Most speaker will work as a very bad microphone.
If you don't get anything, probably your input is not working or ubuntu didn't recognize it. If you get some input, the microphone is dead (usually the case).

(obs: you can also test your mic on another machine or device if available)
