@Ogorek:
Dan Lavry czyli ten z Lavry Engineering (
http://www.lavryengineering.com ) tak jakis czas temu krotko podsumowal:
XLR: for very long distances, even 300 feet, the XLR digital audio it is best due to higher power signals, use of balanced transmission and also transformer coupling.
RCA: weak signals, single ended, no transformer coupling. I find RCA to be the most fragile, but it works just fine if the cable is short enough and of reasonable quality.
Optical: I find it to be more robust then RCA, less robust then XLR. There are no ground loop current issues.
USB: Works fine at low distances, similar results as the optical.

U Ciebie przy tych 5 metrach to przypuszczam juz za daleko i na USB i na RCA. Moze tez dlatego kabel robi roznice. Jak mialem kiedys jakis najtanszy USB z komputronika na bodajze tez cos kolo 5 metrow, to byly problemy z urzadzeniem do niego podlaczonym. Co jakis czas system zglaszal, ze jest odlaczone, pozniej znow je wykrywal etc. Zmienilem go na inny - bylo to samo, na krotkim nie bylo problemow.
