Downloaded the Karmic RC alternate iso, upgraded distribution from Jaunty, no problem with sound.
Then downloaded the Final Release yesterday upgraded and the sound disappeared.
That was quite alarming.

As others have noted the sound card was not being recognised in Hardware profile. Removing the modem driver restores sound to the system. Sound card is once more recognised by pulseaudio.
Weird problem.

My laptop is a Toshiba with the HDA Intel sound chip.
