Solution to this problem: Shutdown the computer (not restart, not reboot, not force-reload), make sure all the hardware is off and the power is off, then start the computer and everything should be working fine.
Hibernating does not restart the hardware properly, which is only done properly when the computer is starting from an off state. -- After hibernate, sound doesn't work https://bugs.launchpad.net/bugs/25896 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
