1) I disconnected my speakers from the rear jack, and plugged my headphones into the front jack. After rebooting, the headphones are detected and the sound works - everything is perfect. I opened the Sound Settings dialog, and "Headphones" are present, "Line Out" is absent.
2) I plugged my speakers into the rear jack, and sound immediately stopped playing from the headphones. But the speakers are also silent, even though they're not muted in the GUI. I try muting and unmuting, switching between headphones and line out in the GUI, but nothing works - neither the speakers, nor the headphones. these are pulseaudio bug since you don't have the above patch, line out jacks are muted by the driver headphone are muted by pulseaudio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1442428 Title: Headphones not detected after fresh boot or suspend/resume cycle, until unplugged and plugged back in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1442428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
