Hi James,
obvious one, did you try to restart pulseaudio?
See lower, PA is using 'Dummy output' sink and for some reason your
ALSA sink is no longer known. I think I encountered this problem once,
but I was unable to reproduce it after reboot.

After the last tumbleweed update, I've lost sound through my laptop's built-in sound device, and through it's docking station. (This is my first failure ever with Linux audio, so I guess I had it coming.) This is a Dell Latitude E7450, BTW.
I know pulseaudio and any underlying subsystems are working - if I plug in a USB audio device it's recognized and usable immediately - so I assume it's a driver issue with my hardware.
