This bugfix is part of that upstream stable update for Lucid to
2.6.32.12 (see Bug #575853).

(Card0.Codecs.codec.0.txt) has revealed that my 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.

How do I know this? Because Daniel Chen told me so in bug #548661.
Thanks Daniel!
