Usually I've been able to resuscitate the audio by reinstalling all the audio drivers, as suggested on the audio troubleshooting page for the Ubuntu community. The last time, however, this did not work and I had to install the latest ppa audio, after which audio came back. Now, nothing seems to work. I know the sound card and audio systems are fine--the machine is a dual boot and audio works without problems with Windows running. Ubuntu 'sees' the sound card, at least according to sysinfo. But, my sound system settings shows "Dummy Output," no microphone, and no hardware. I'm guessing that something left over from the hard reboot is blocking the system's access to my audio card, but can't seem to find anything online with suggestions for a fix. I'd say the problem is a bug because I'd hope Ubuntu would be robust to an occasional hard shutdown.
