When i plug in headphones in front panel the sound still comes out the speakers.
I have to go in to alsamixer to switch from multi-channel output to Front Panel Headphone output, than i have to go in sound settings and select the headphone output instead of the 5.1 one output, than finally i can hear the music , movies in my headphones. But this is irritating me… i have an asus xonar dg sound card that is detected out of the box… but…no matter what headphones i plug they are not detected.
