Every once in awhile, after gnome-session crashes or after waking my laptop from sleep, the only audio devices available to the system are “Dummy Output.” I have to reboot to get my audio devices back.
I’m on a Thinkpad P50.
lspci reports that my device is:
01:00.1 Audio device: NVIDIA Corporation Device 0fbc (rev a1)
Any thoughts or steps on how to troubleshoot? It would be nice to not have to reboot when this happens. Thanks!
