Using the Indicator Sound applet on Ubuntu 12.04, I changed the Hardward output from "Analog Stereo Duplex" to "Analog Stereo Output" and I've lost the card reference there, no more sound. In Output appear "Dummy output" and in Hardware I don't have my built in card showed anymore.
Information attached.
