Public bug reported:
I'm experiencing a strange behavior with a headphone jack on my laptop.
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.
