Public bug reported:
Since kernel 3.0, the position of 0db for the PCM channel on this
CS5535-equiped Geode-based hardware has changed to a lower value that
results in barely audible audio at default settings. According to
'alsamixer' the 0db level on the PCM channel used to be at position 74,
but nowadays it's at position 54.
