I just found out how to make my headphone work, really simple, only two steps:
step1. Shutdown step2. Boot *ATTENTION* reboot won't work. only boot after a shutdown can make it work. no matter if I reboot from Ubuntu or Windows 7, My Headphone never works. but if I shutdown from Ubuntu or WIndows 7, then boot into Ubuntu, my headphone will work perfectly. Well, I really don't know why. Anyone knows how this works, please send me an e-mail, I'll be appreciate ^ ^ ! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1087428 Title: [K55VD, Realtek ALC270, Black Headphone Out, Right] No sound at all Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: My headphone jack does not play any audio, but my laptop speakers do.
