BUG: unable to handle kernel paging request, RIP is at patch_generic_hdmi+0xe0/0x550 [snd_hda_codec_hdmi]

[Jay Foad]

On upgrading from Ubuntu 12.10 to 13.04, I found that sound has stopped working. If I go to System Settings... -> Sound, the only option in the "Play sound through" box is "Dummy Output".

I noticed that there is a kernel oops in my dmesg which looks related.
