USB cards by chance? This is a known problem with USB Audio. Well actually
with USB in general. I am coming to the realization USB audio devices are
not desirable for profesional audio. They are sort of the best one can get
on a limited (reasonable?) budget. It is unfortunate that USB has become
the way periferals are added on modern computers when it comes to audio.
USB is great for many other things from printers to mice, but not really
critical audio.
