By DAC levels, do you mean the mixer levels as visually represented by
alsamixer? The mixer levels don't change. The PCM level is the one I
can adjust to fix the problem, and it remains steady at 469 (92%).

I'm still tempted to think of it as a software problem, if only
because it goes away when I tweak the levels. I don't have any idea
where to start looking for such a problem, however.

I've been talking to the manufacturers about it, and they've had
trouble duplicating it. It's hard to imagine that a card I paid
hundreds of euro for could be this unstable. Unfortunately, I can't
afford to buy another one to swap in to test the hypothesis of a
faulty card.

Could temperature be an issue? The environment is pretty warm.
