Pulseaudio will not connect either- "connection refused" it says.
Reading these four snippets, Karmic has identified the Intel hardware (1) and loaded the correct driver (2). What command generated the UNCLAIMED message (3)? Possibly the "connection refused" (4) is because the hardware is already in use.
I think possibly the volume is muted somewhere. Karmic changed all the volume settings and introduced per-application volume setting. Have a look at System -> Preferences -> Sound (or right-click on the speaker applet) and check that there is unmuted output in the first tab, hardware set to Ananlog Stereo Duplex (or Analog Stereo Out) in the second tab, the third tab sets microphone, the internal output is enabled in the fourth tab and whatever application you are trying appears in the fifth tab if necessary.
Also, start your multimedia application from a terminal to catch any errors or warning about misconfigured hardware.
