I have Ubuntu Jaunty on a Lenovo Thinkpad.This problem specifically occurs when using a headphone. Everytime i mute the sound using the keyboard's multimedia "mute"key and then unmute it, i can hear sound from both the headphone and the laptop's speakers. This doesnt happen if use the volume icon in the tray to mute/unmute. Also, everytime i plugin a headphone i have to use alsamixer to change the output to "headphone", if i dont change it, there's no sound in the headphone. Doesnt Ubuntu detect by default if a headphone is plugged in like in (i dare say not) Windows? Thanks for any help.
