[Jeffrey Tees <1313813@xxxxxxxxxxxxxxxxxx>]

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).

Title:
  amixer 'mute toggle shortcut' problem (can mute but not unmute)

Status in “alsa-utils” package in Ubuntu:
  New

Bug description:
  Openbox shortcut configuration file on ~/.config/openbox/lubuntu-
  rc.xml triggers to the following command to be executed:

  $ amixer -q sset Master toggle

  This problem is language related/dependent. This works fine on a pure
  english Lubuntu installation (toggle behavior). I installed Portuguese
  language package, on this very same machine, and now shortcut can
  mute, but I need to use the volume control on "tray" to unmute!

  I can solve the issue by running this command:

  $ amixer -q sset Master toggle && amixer -q sset Speaker unmute &&
  amixer -q sset Headphone unmute

  A good workaround is edit  ~/.config/openbox/lubuntu-rc.xml and
  set/reset this config.:

      <keybind key="XF86AudioMute">
        <action name="Execute">
          <command>amixer -q sset Master toggle</command>
        </action>
       <action name="Execute">
  	<command>amixer -q sset Speaker unmute</command>
       </action>
      <action name="Execute">
  	<command>amixer  -q sset Headphone unmute</command>
        </action>
      </keybind>
