Jane, For easier debugging, we would like you to reproduce this symptom using the latest alsa-driver snapshot. Please add the ubuntu-audio-dev ppa[0], ensure that you are running 2.6.32-18-generic (from uname -r) installed, install linux-alsa-driver-modules-$(uname -r), then reboot.
Not directly related, but reading your machine's codec dump (Card0.Codecs.codec.0.txt) has revealed another bug (should be reported separately using ubuntu-bug alsa-base) that your PCM level is overdriven; the offset to 0 dB (which should correspond to 100%) is 0x3d, but the number of steps is 0x3f, which means anything set at 100% will sound distorted.
