Well, it looks to me like this is caused by the fact that the audio cards clocks
are not in sync. When you loopback card A with itself, both input and output are
sampled with the same clock. But when you plug the output of card A into card X,
you're dealing with two clocks which are not synchronized, and that result into
these "artefacts". If I'm right then you should observe some /similar/
issues
when repeating the experience with the cards inverted.
The clocks don't matter, as the connection is via an analog signal.
