@David, I think you are right. I have been getting occasional kernel oops as well, it sounds like the issue I've been having. ** This bug has been marked a duplicate of bug 1169984 Either oops or opening device fails with -ENODEV, with HDMI audio -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1171181 Title: Random Pulseaudio "Dummy Output" Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: I cannot manually reproduce this and it seems pretty rare/random, but I've noticed in 13.04 at random when I boot up pulseaudio isn't working at all. It just shows a "dummy output". rebooting has fixed it each time it happened. I also noticed each time I saw this happen there was an accompanying hang on reboot, it would just sit at the plymouth splash and I'd have to use the power button. My theory is that sometimes pulseaudio fails to start correctly causing the dummy output issue, and when I reboot it also fails to exit causing the hang. I've seen this on both of my laptops, one running ubuntu 13.04 fully updated one running xubuntu 13.04 fully updated.
