Hi, I've searched around for a solution to this problem and have discovered that many others are having the same problem but no one have been able to resolve this issue. I've recently installed Linux Mint 12 (mate) on my mom's Fujitsu Lifebook n6110. Everything works out of the box except for one thing. When she plugs the headphones in the speakers continue working. The work around I have found is to open up alsamixer through the terminal and lower the speaker volume there. I have no problem with that but my mom is not very teksavy and I would like it for her to be as user-friendly as possible, therefore not having to make her go through the terminal. Is there a better permanent solution to this problem?
