I've actually measured this with an oscilloscope (because I'm that sad,
and to settle an argument), and at least the DA converters I tested did
respect the fact that the peak voltage was obove the INT_MAX voltage level.
It was a few years ago, so I cant remember what I tested, but one thing
was a yamaha digital desk.

It could be. OTOH, most DACs today would upsample and filter before the
real conversion takes place, and could allow for this. But maybe they
don't, and just clip at that point. 'THE SAMPLES ARE NOT THE SIGNAL'. The
real peak level of a
signal when converted to the analog domain can be several
dB above that of the highest sample.
indeed. there are people who are coming to believe that this "error" is
responsible for a significant part of the audible difference between
digital and analog playback when the levels in the source material are
high.
