Also affects Ubuntu 14.04 Vanilla (running standalone Xmonad Window Manager, not Unity Desktop on Acer Aspire One D260).

amixer -q sset Master toggle (or Master,0) also mutes Headphone and Speaker but does not unmute Headphone and Speaker when run again to unmute.

Problem persists whether system plugged into speakers through headphone jack or not.

Work-around also fixes problem for Xmonad (and also Herbstluftwm and other window managers) on vanilla Ubuntu.

I have no additional languages installed (Native English speaker) , but ibus is managing keyboard (as default in 14.04).
