Sometime during the 13.10 release cycle the problem was fixed in the kernel. Now in the 14.04 after a kernel update sound no longer works. I'm not 100% sure which kernel update broke sound. I will try to install some of the older kernels and track it down. Alsa and PulseAudio both show that the sound is turned all the way up, but no sound plays and the sound tests fail to make any noise too.
