I am also having this problem with a similar hardware setup on Karmic with kernel 2.6.30-10-generic and pulseaudio 0.9.15. I have a webcam with built-in microphone and an Intel HDA ATI SB.

When running pulseaudio from the command line, and then testing the sound output using the configuration dialogue (System->Preferences->Sound), the tone produced may play for a fraction of a second, and then produce an output stating that:

W: alsa-source.c: Your kernel driver is broken: it reports a volume range from 18.00 dB to 18.00 dB which makes no sense.
E: alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 13258597302978738736 bytes (209146758196 ms).
E: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

Followed by snd_pcm_dump() output (see attached file) and then pulseaudio terminates with:

Soft CPU time limit exhausted, terminating.
Hard CPU time limit exhausted, terminating forcibly.
