hw0,Juli & hw1,Juli seem a bit weird. Do you mean hw:Juli,0 & hw:Juli,1?

If you want to use the analogue inputs tell jack to use hw:Juli,0
If you want to use the S/PDIF input tell jack to use hw:Juli,1
If you want to use both, use alsa_in/zita_a2j on one of them.

(You may be able to use device combining if the card lets you clock
everything together.)

This may happen if there's no S/PDIF signal, as then there is no clock
for the card to sync to.
