Trying OpenPCI on WinUAE is just nonsense. WinUAE does not emulate any PCI board. The same is true for the Maestrix driver, especially if you try to redirect Maestrix calls to AHI which will cause an infinite loop.
You should rather remove PCI and Maestrix drivers from Devs/Audiomodes and Devs/AHI. Only keep those drivers in there for which you have hardware, i.e. UAE and Paula. You might even omit Paula because UAE has much better quality (accesses the PC sound card directly rather than emulating 8bit sound).
