Thank you, that was the culprit for one of the Terratec cards. Indeed once upon a time I tested S/PDIF to help Jeanette. Since I used the Terratec cards just for MIDI, I seemingly have forgotten to care about the audio settings. If I built in the other Terratec card, most of the times the PC doesn't boot, it even doesn't load the BIOS. If it should boot with both cards mounted, aplay does only show one of the two cards. It never booted, when only the fishy card was mounted, without the other card being build in, too. So one issue is solved, because it was an user error, but now there's most likely a hardware issue, when the other card is plugged in a slot.
