I own Toshiba Satellite Pro C650 and it is running Ubuntu 10.10. I also have Windows 7 installed on other drive.
My notebook has built-in speakers and an audio output jack. In Windows 7, when I plugin an my headphones into the jack, the speakers stop and the sound is played through the headphones. But, it doesn't work in Ubuntu. Even the Hardware tab in Sound Preferences dialog box shows only one audio device. Can you please help me out?
P.S: I've just migrated from Windows 7 to Ubuntu. But I cannot uninstall Windows 7 because I need the "mute speaker, play headphones" functionality as I do not want to disturb others. This is the only reason, Windows 7 is still there on my laptop.
Edit: I wasn't clear. Headphones do not work at all. There is also another problem: My input device does not work.
