I have had no sound out of my laptop since I installed Debian overtop of Windows 10. Sound worked just fine in Windows, but nothing I have done has been able to bring it back since the install.
I'm running Debian 9 on a Dell XPS 15 (9570) with XFCE on top of lightdm.

I see a common fix of killing pulseaudio and restarting it. I have tried this, and it does nothing. PulseAudio dies, restarts, and behaves the exact same way it did before.
Does anyone have any ideas as to why my audio isn't working?
