I'm running the testing branch of debian with codename
Jessie and xfce as desktop environment on a Lenovo ThinkPad T410. When I press the mute-button, it mutes pulse-audio and alsa, but when I press the mute-button again it unmutes pulse-audio but not alsa. I can happily mute and unmute in the terminal by
amixer set Master toggle
Now I'd like to set this command to be executed when pressing the mute button. xfce has a setting for that, it works for other buttons, but not the mute button. In
.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml I have the line
<property name="XF86AudioMute" type="string" value="amixer set Master toggle"/>
but to no avail. Does anyone know how I can either turn off the mute button or overwrite what happens when I press it?
