I solved the noiseproblem with balanced/ symmetrical audio cables
together with card and mixer with symmetrical connectors, in this case a
Hammerfall Multiface and a big mixer but some of the small ones like
Tapco and Behringer should have balanced inputs too, I know that the
small Yamaha Mixers dont.
Cheers,
Malte
