You could write a wrapper for ioctl. I had a few ideas on this but you
might not even need to do that. Would ws2_32 ioctlsocket and WSAioctl
maybe work? You might have to add a static lib that does a WSAstartup
to each sound driver.

You might find something of use there. Also check out how Wine uses
ioctl to enumerate the devices in wine/dlls/iphlpapi verses
