The trick works inserting "ifconfig wlan0 down" (or the active network interface in use) at the begining of the stop) section of /etc/init.d/alsa-utils.
I'm sure it's not network-manager related, my laptop also hangs uninstalling the package and starting wifi via wicd.
Btw, if your alsa-mixer is always mute at system start, and does not remember the last settings, the trick also fixes it.
