This sound card does not have the ability to react to irq7. There are simply no wires and chip inputs for it.
The card is initialised with PNP on startup at irq5 or 3 (if 5 is not available) and not configurable.
I found out if i reroute the irq5 signal from the card to irq7 of the mainboard, the card still initialises normally and says its using irq 5.
But now i can use irq7 in games. Thats pretty nice for games that only use irq7.
Now i can implement this new knowledge into my final design. Great.
