Hello,
I have already read most of the posts in internet related to: ubuntu sound problem, trubleshootings, ekiga sound problem, mic sound problem, capture audio problem, pulseaudio (already killed and removed), ALSA, gnome-volume-control (evrything is red, nothing is unmuted), alsamixer: see my .png
This are the output of the commands that are normally required for people being able to help you:
arecord -l:

I can hear all kind of test through my headphones

I can hear all kind of sounds in youtube, in shockwave, in adobe, mp3, wav, audacity, rythmbox, and totem; play sounds fine.

I just cannot use my mic either in ekiga, either in sound recorder, either in audacity.
My mic is a SPEEDLINK headphones with mic that I plugged in with a jack.

Dear all,
after nobody answering, I upgraded to 10.04
and in this link I found the solution: http://ubuntuforums.org/showthread.php?t=1504904
I decided to mark it as solved because I cannot try it anymore with ubuntu 8.04, but I have the feeling that if the set up of "alsamixer" will have the mic controls in playback 'mute', it should work.
If anybody needs more help, I will be glad to answer them
