Thank you so much for your answer!
The noise is ever present in Linux as soon as it is initiated. The noise
is slightly better the higher sample frequency in Jack, but even without
jack there is static noise and crackles. I just realised that I I have
not checked whether this is on the headphone outlets only - but this
seems unlikely since we had the problem on the recording the other day
even after exporting to another computer with another interface. I'll
check it though.
Thanks!

So - dear clever people: Should I abandon the card or do you have some
ideas for a possible solution for me?
This is a very specific issue and I can't help with that
unfortunately, but I have been using the smaller version (M-Audio Fast
Track Mk II) at home without any issues for years now. However, it
does not like odd values in JACK (e.g. 44,1 kHz or frame rates that
are not the power of 2), then it will produce crazy noises once in a
while.
Maybe your problem is similar and a configuration issue? To narrow it
down: What happens when you turn JACK off and run the card regularly
through ALSA/Pulseaudio? I wouldn't do serious recordings that way,
but does that get rid of the noise at least?
