amixer toggle mutes but does not unmute

It seems that the common approach to mute the audio in Ubuntu 13.04 is amixer -q sset Master toggle ... which works great when muting, but fails to unmute. This command is, for example, the default for openbox's handling of XF86AudioPlay shortcut.

I have no idea why this works this way and why it doesn't undo what it did... and, frankly, I don't really care that much. It's much easier to code around this, see the following workaround script:
