I have the same problem. My audio section from lspci -v gives:

00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)
 Subsystem: Intel Corporation Device e001
 Flags: bus master, medium devsel, latency 0, IRQ 17
 Memory at febff800 (32-bit, non-prefetchable) [size=512]
 Memory at febff400 (32-bit, non-prefetchable) [size=256]
 Capabilities: <access denied>
 Kernel driver in use: Intel ICH
 Kernel modules: snd-intel8x0

Setting ignore_dB=1 doesn't seem to help at all. Running alsamixer and reducing gain to 0 on PCM fixes it though.
