Prinz Igor:
I have the same sound card as you have but have not been able to fix it with
the fixes mentioned here. My hardware (laptop Fujitsu-Siemens Amilo Pro V3205)
has an internal microphone which works good (though it has a quite low volume).
You could try that one by opening up the GNOME Volume Manager, press
"Switches"-tab and then "IntMic". Make sure it is not muted or anything (I had
to use "alsamixer" and go into "Capture"-mode to do that)...
Everyone else:
You are mentioning that you have a tab called "Options" in GNOME Volume
Manager. The only tab I have are "Playback" and "Switches". Are the tabs in the
Volume Manager audio device dependent or do you have a different version of it?
The version is I'm using is '2.18.0'.
As I wrote to Igor I am experiencing the same problem (external
microphone is absolutely quiet but internal microphone works) but the
fixes you mention don't work for my (similar) hardware:
$ sudo lspci -vv
