Pls help me.

I am trying to get and set the properties of soundmax card.Both get and set uses deviceiocontrol.The get version is working fine but when i set the pin state to RUN ,the deviceiocontrol fails returning error ERROR_BAD_COMMAND.There are two kinds of cards on my m/c.One is soundmax and the other maudio.For maudio it works fine but it fails for soundmax.I am running vista on my m/c.

If anybody had the same issue pls let me know if any solution exists for the same.Thanks
