I don't know if this has a bearing on the problem you observed, but (at
least in Lubuntu 12.04) I have had to change the
"/etc/modprobe.d/alsa-base.conf" file (in the case where you have two or
more sound cards), so that the one not hooked up to the
speakers/amplifier will not get the first slot.
It would usually initialize them in the same order, but occasionally,
there would be no sound, and I would notice (looking in the qjackctl
configuration) that the sound cards had opposite slots (were initialized
in a different order).
In Ubuntu (and Kubuntu) you can indicate which sound card you use, and
it will respect that specification. That has not been the case with
Lubuntu (11.10, and 12.04, at least).
