Ok, a 64-bit openSUSE-11.1 with the 2.6.27.29 kernel and an AD1988B hardware audio codec.

I note this in your mixer settings:

!!Amixer output

I note you have Front Mic muted (off) and its boost at 0. That should be ok, IF the mixer is mapped correctly. But you have the mixer mic-0 OFF, and its boost only at 33%. And you have capture-1 and capture-2 muted. Until you establish of capture 0, 1, or 2 is controller for you mic, it may be prudent NOT to mute those. Once you get the mic working, then you can selective mute the ones that do not matter via trial and error.

I did a search for the AD1988B on the alsa web site, and I did not find any new updates: Search results - AlsaProject

If looking at the mixer aspects I suggested does not work, you could try to force the alsa configuration upon boot to a specific model. Below is a list of the model options for the AD1988B:

Code:

	AD1988/AD1988B/AD1989A/AD1989B
	  6stack	6-jack
	  6stack-dig	ditto with SPDIF
	  3stack	3-jack
	  3stack-dig	ditto with SPDIF
	  laptop	3-jack with hp-jack automute
	  laptop-dig	ditto with SPDIF
	  auto		auto-config reading BIOS (default)

One can apply those settings, ONE at a time, to the /etc/modprobe.d/sound file. Example syntax, for example option "laptop" from that list, the edit to the /etc/modprobe.d/sound file would be:

Code:

options snd-hda-intel model=6stack
options snd slots=snd-hda-intel
# 5Dex.8qRx2YE_Lv8:SBx00 Azalia (Intel HDA)
alias snd-card-0 snd-hda-intel

then restart alsa with su -c 'rcalsasound restart' and enter root password when prompted and restart one's PC's mixer and then test. Test thoroughly. Take a look if your mixer settings are worse or better. Some of these options may break one's sound. If "laptop" does not work, pick another item from list such as "3stack" and replace "laptop" in the /etc/modprobe.d/sound file with "3stack", restart alsa, restart mixer, and test. Try each of those options, one at a time.

I have feeling that something stupid is hapenning, but I still can not get the mic to work. When I try to select any option (model=6stack, for example), after rcalsasound restart I get the following message:
Shutting down sound driver done

----------------
When I remove model option, sound works, but no microphone. One thing that confuses me all the time is that mic responds to Kmix very well: I can hear mic echo, (un)mute, increase boost, everything works, but nothing can be recorded with arecord or Krecord

No, that is expected for many of the options. Try each option. One or more of them will work better.

That could be your mixer. I gave you some suggestions as to what you need to look at on your mixer. Thats all I can do there.

Its also possible an update to alsa 1.0.21 is necessary, and I can help give you the zypper commands for that if need be, but first try EVERY option that are in the list I provided.

I am happy to say it works now! Problem was with connectors mapping, when I plug in mic in rear connector, it requires 'front mic' to be selected and boosted. It doesn't matter if the mute is selected (I keep it muted to avoid echo). Skype now works well

Thank you very much for help!!!

Glad to read it works.

If I may offer a suggestion, take a screen shot of your working mixer configuration, and place it somewhere easy to find. I do this for my wife's openSUSE (I keep it on her desktop). Without that, she forgets the mixer settings and rants at me about Linux poor functionality, when in fact it is her misconfiguring the mixer, and forgetting the functional settings.
