I'm on the XPS 9360
Suspending the laptop makes the headset detect for me but they
headphones still don't work and the speakers stop working after that
too, it doesn't matter what I select under 'sound'. It then seems to
need a reboot to get the speakers back again (although I'm not 100% on
auto muting is disabled and I'm loading the snd-soc-rt286 in
/etc/modules (as I only get sound from the left speaker otherwise).
USB speaker works fine.
None of my microphones work.

[XPS 15 9550, Realtek ALC3266] Headphone jack stops working after a
Status in alsa-driver package in Ubuntu:
I'm experiencing a strange behavior with a headphone jack on my
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
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.
