The overdriven sound seems to no longer be happening on Karmic or Lucid. Though I'm puzzled since according to my notes, I did see this in Karmic previously, and I don't see any changes to pulseaudio in Karmic that I feel should have fixed it. I may do some more testing with the original pulseaudio in Karmic tomorrow.

Strangely, the pulseaudio volume control in Lucid didn't adjust the alsa volume at all for the DA40 adapter. It seemed to be a software volume control only. This meant that if the alsa volume was turned down, pulseaudio was unable to turn it back up. This wasn't the case for the internal sound card, nor was it the case in Karmic.
