/var/lib/alsa/asound.state records your mixer settings so they persist
across reboots (see alsactl(1) for details). That is why I suggested
removing it between shutdown (when they are recorded) and system
initialization (when they are restored), making sure to remove power
so the sound card would not have any lingering state either, to see
what value the "auto-mute mode" control gets for new installations.
If it defaults to false, that would be a bug that we could pursue
Similarly, I am still very interested to see what value the
"auto-mute mode" control gets on upgrade from squeeze, hence the
second set of instructions.
Hoping that clarifies a little,
