Audio doesn't work anymore after recent kernel updates

I'm on maverick 10.10; fully updated.

In the user.log file, it is stated that:

  1 Mar 19 10:18:49 quadian pulseaudio[1808]: alsa-util.c: snd_pcm_avail_delay() returned strange values: delay 0 is less than avail 40.
  2 Mar 19 10:18:49 quadian pulseaudio[1808]: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

So I'm reporting it here.
