kernel error message from pulseaudio

[Paolo Galtieri]

I see lots of the following message

Dec 13 23:56:17 localhost pulseaudio[2050]: alsa-mixer.c: Your kernel driver
is broken: it reports a volume range from 18.00 dB to 18.00 dB which makes
no sense.

Can anyone tell me what the cause of this is and how ti fix it?
