Actually, the ens1371 is a particularly bad card for/good example of 
maintaining sync at the sample level.
The (at least the one I have) ens1371 has a bug where the sample rate is one 
short (or long, I forget) on the capture side.
The result is when you play back a large audio file at 44.1 it's not the right 
length. The difference over an hour is about 2 seconds.
