I'm sorry to 'up' such an old topic, but searching for an answer before posting a new topic I found this one. I'm having this same problem, though with a 4 channel card (model RX-7404).
Does anyone have any idea if there is software out there compatible with these cards?
If no software is known for this card, a suggestion for a reasonably priced alternative for this card is also appreciated.
Thank you very much for your help!
Kind regards, Jochem Kuhnen, the Netherlands.
