I have an external audio speaker connected to it. When I disconnect the speaker and reconnect it again it stops working. Even more, laptop audio stops working too. And after the reboot, I don't even see any of the audio devices. I've googled a lot and tried different fixes from forums with no luck. After a while, I've accidentally discovered that putting the laptop to the sleep mode and rebooting system after brings audio back to live. Even more, if speakers were attached during this sleep-reboot procedure, they are starting to work as well. However, after the next reboot speakers are not working again. And if I will plug them out and in - problem with completely missing audio returns. P.S. I'm using laptop-mode-tools package on my laptop. Recovery after hibernation made me believe that it's somehow related. But after uninstalling this package nothing really changed.
