15.04 no sound “Dummy Output”
I have a Dell Latitude D630. When I reinstalled Ubuntu 15.04 from a DVD after an update, it left my laptop inoperable. Now the only sound option under audio is "Dummy Output". I have tried advice from other sites, but nothing helps. The options listed here do not apply to my 15.04 problem.

Ubuntu uses ALSA as a sound driver, but PulseAudio acts as a man in the middle, interfacing between ALSA and the various programs on the computer. PulseAudio is supposed to be able to, for lack of a nicer term, "hijack" the sound card. However to to so requires that PulseAudio be the only program accessing the sound card directly.
The first thing I would do is try restarting PulseAudio using pulseaudio -k.
If there are other programs accessing the sound card, they need to either stop accessing the card, or be shut down. The best way to find out which programs are accessing the sound card is to run sudo fuser -v /dev/snd/*. You should see the names and PIDs of any programs using your sound card. If you see anything other than PulseAudio, you can shut it down using the kill command. Assuming the problematic PIDs are 12345 and 67890, you can use kill 12345 67890. If the programs accessing your sound card are being run by some user other than you, you may need to use sudo to run kill with root privileges.
PS: The Arch Linux wiki has a very detailed article on troubleshooting PulseAudio. If none of the above works for you, maybe something there will.
