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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1087428 Title: [K55VD, Realtek ALC270, Black Headphone Out, Right] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1087428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
