[LAU] Testing sync with 2 sound cards

[Joe Hartley]

I was recently fortunate enough to pick up a second Delta 1010 for my
studio.  I know that it's important to run these in such a way that one
card's clock is slaved to the other.

What's the best way to ensure that the cards are actually in sync?
I've recorded an hour of a metronome in Ardour with the signal split
to an input on each card and saw no drift between the tracks.  I then
played them back and heard no drift even after 30 minutes, but I have
a feeling that this isn't necessarily a valid way of testing.

Thanks!
