Still no luck, restoring from your settings Kacper:

$ alsactl -f asound.state restore
Unknown hardware: "HDA-Intel" "Realtek ALC889A" "HDA:10ec0885,106b3f00,00100103" "" ""
Hardware is initialized using a guess method
alsactl: set_control:1266: failed to obtain info for control #32 (No such file or directory)
alsactl: set_control:1266: failed to obtain info for control #33 (No such file or directory)

I get nothing when recording, sliding the sliders up and down, clicking
the little mic icon to supposedly mute/unmute the mic, just nothing.
When I close and re-open Volume Control, all the mic channels are shown
with the muted mic icon, too, just as I mentioned in the forum thread
linked to above. Something's inconsistent between our setups. Is there
any more information I can give to help pick out what's going wrong? Are
there any files I can delete to restore to defaults?

Bug description:
Reporting this bug for another user...

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.

This bug is confirmed by several users, see the additional information attached.
