Rationale
I am using Ubuntu since Dapper, and still have problem with my microphone.
First I had AC97 chip built-in, then I bought a soundcard (Muse) and deativated the built-in chip.
But still need to shout in the microphone to be listened. It might be a configuration issue, adjusting/tweaking volumes and others in Alsamixer...
But I have to say that on Windows, once your sound card works (ie you use the right driver), your microphone just works.
I find it really painful, and had to give up for now, without success.

I have this same type of problem on lots of systems, really frustrating if you want to use a voip softphone.

+1 ! My microphone never worked since I joined the Ubuntu community more or less two years ago. It appears Hary Heron is going to make some improvements with the sound management on Ubuntu by resolving the issues of conflicts between application trying to get a full control under the sound device. Now the Ubuntu team is looking on that side, it should be great that you don't fix the microphone issues ;) !

I have the same problem too, since switching to Ubuntu. Microphone worked excellently when I was using Windows.

I agree. I've been in since dapper, with hda nvidia chip, and it has never recognized that I have a microphone jack in my computer.

Do you really think that this is your idea and no one ever thought about this before? You should report this as a bug in launchpad. But before you do that just check if you mike isn't muted. Mine was muted at 4 different places by default. I unmuted all of them and it works now.

to krycheck :
No, it is not my idea, and as I said it might be a configuration issue... but complex to fix. I bought my Muse soundcard only for that reason, but it was the same.
The problem behind this could be as you said "Mine was muted at 4 different places by default".
Why is it muted by default ? at 4 different places ? how can a simple user go through this without being frustated ?
This might be enhanced, don't you think so ? this is why I created this "idea" : makes microphone works (like speakers works) without doing anything special. With today popular apps like Skype (or Ekiga), that device is REQUIRED.

+1 The builtin mic on my thinkpad t43 is so quiet that I need to plug in an external mic to use skype properly. But it works fine on Windows.
I guess it's possible that the Windows driver is over-amplifying, making the input sound louder than it really is (which usually means it'll be distorted.) If so, then it would be bad to make it louder by default, but I'd still like to see an option to over-amplify if you want to, so I can use a quiet mic. Currently all my sliders are set to the max, and it's still not loud enough.

That's a good idea, because my microphone doesn't work on hardy. I've a Asus P4P800 motherboard, if you have an idea for me !!
I tested a lot of things, without results !

I think sound device management is needlessly difficult in Ubuntu, and this is one of the only things that I miss about XP. +1 to this idea and any other one that simplifies the use of different sound input and output devices.

Standard sound chips of supported motherboards should be recognised in full during installation. Like PLED said earlier on. A working line-in mic is NOT a nice to have anymore.After about eight months of hassle and frustration guess what... still no application that will work with the mic. It does work like a snap on an old WIN2K machine.

00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)
(lspci -n)
00:10.1 0403: 10de:026c (rev a2)
Ubuntu 8.04
System->Preferences->Sound - ESD is turned off, on Devices tab all selected to ALSA.
Sound Mixer applet: Playback tab: General, PCM, Mic, Mic Boost, Mono.
1. What's Mic Boost and Mono?
ok, if Mic of Mic Boost not muted, I hear my voice in headphones when I speak to microphone- it 100% connected and works.
Record tab make me confused: only "Capture". Ok, it is ON.
Switchers: Mic capture, Phone, Mono capture.
I select Mic capture.
Try to capture sound:
$ arecord -f cd testfile.wav
result is file with silent.
$ hexdump testfile.wav | less

What's AUX ? What's MONO? What's IEC958???
So, I try different combination but can't record sound with arecord and gnome-sound-recorder at all.
