`alsactl` holds its state in /var/lib/alsa/asound.state, which I had
explicitly deleted, and then did a quick shutdown (sysrq+u&s&b), so the
shutdown scripts would not recreate it. All volume levels were back to
their defaults, just as expected. But skype still worked basically with
the same configuration that I had when it was _not_ working.
It is almost like there is an additional place that holds the state that
I am not aware of.

The reason I started digging for it was that skype was extremely choppy.
I would be able to complete the test call as only one side would speak
at a time, but a real conversation was a nightmare. First I suspected a
duplex issue, but after your answer I tried arecord/aplay combo and it
worked. So I looked deeper and found some references to asym. I decided
to give it a try and created the following .asoundrc:
pcm.card0 {
type hw
card 0
}
pcm.dmixer {
type hw
card 0
}
pcm.skype {
type asym
playback.pcm "dmixer"
capture.pcm "card0"
}
pcm.!default {
type plug
slave.pcm "skype"
}
Skype started working. However I needed !default to be a different card,
so I just started testing different configurations of stuff and all of a
sudden realized that skype _still_ works, no matter what I do. I removed
the .asoundrc, emptied /var/lib/alsa, reordered modules so the skype
card becomes card1, shut down the machine completely - skype still
worked after everything I did. On one hand I got what I wanted, on
another I am really irritated since I have no idea what happened, and
how did the change become permanent. Could someone point me in the right
direction? Thanks!

[Alsa-user] Full duplex on nForce 250Gb
Hi, I have an onboard sound card that I know for a fact is full duplex. Alsa picks up the card fine, and everythign works except for full duplex itself. All the info I was able to find is pre-dmix era, and looks very dated. What steps do I have to take to enable full duplex? The relevant information is included below, the kernel is vanilla 2.6.18.6, no patches.
