Since upgrading to Ubuntu 14.04, whenever I wake my laptop out of suspend, its previous volume settings are forgotten and the volume is unmuted and set to 100%. Obviously, this is annoying if I open my laptop in a public space. This also occurs whenever I turn my laptop on (i.e. it doesn't remember that I turned it off with its volume controls muted). What should I modify so that my laptop remembers its pre-suspend volume settings?
Edit: I'm running Ubuntu 14.04 Trusty Tahr on a Dell Inspiron N5110.
/etc/pulse/default.pa, I already have the lineload-module module-device-restore. I'm not sure why the module isn't setting the system volume accordingly, but I'd rather not set it to be muted by default when I open my laptop if I can instead restore its proper functionality. – Michael L.
