Sound comes out of my speakers even when headphones are plugged in
How can I mute the speakers when the headphones are plugged in?
I have searched all over the internet and although there are many threads that discuss this, none has worked for me.
I have tried alsamixer and installing linux-backports-modules-alsa-lucid-generic, but neither worked. The Speakers just wont mute when I plug in the headphones. I had this problem in 11.04 and hoped it would be one of the headaches to go away when I downgraded to Lucid Lynx.
