do you mean headphone still not working ?
did you plugged in headset or just headphone ? do you need to use the jack state of node 0x19 reflect the jack state of mic 0x18 ? the main point is if line out does not support jack detection , it cannot auto mute the internal speaker although you can use hints to disable the channel mode (surround 51) multi_io = false https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa /HD-Audio.txt the driver seem unable to create "Front Playback Volume" for the Line Out jack -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1026847 Title: [MacPro5,1, Realtek ALC889A, Green Headphone Out, Front] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1026847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
