alsamixer misidentifies the speaker channel as a headphone. In fact raising one of the headphones channels allows the speakers to work.
The problem returns the next time you use the headphones, as the computer will lower the volume to zero once again as you plug out the headphones from the jack. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1606078 Title: No sound with Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1606078/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
