Just confirming that Daniel's diagnosis and proposed fix works. While waiting for the new version, I've tested by creating a (temporary) symlink from /sbin/alsactl to /usr/sbin/alsactl, and audio works again after a reboot.
Thanks, Daniel! :-)

Matteo, there was no asound.state prior to my manually doing a store, and nothing would have been restored, which all makes sense, given the nature of the defect. But all works now.
