I have no specific reason to think it's AMD incompatibility -- but the Csound code is tuned for nocona, i.e. Intel Core 2 Duo. I will research this a bit.

Csound itself is built with MinGW, the PortAudio library is built with Microsoft Visual C++ Express Edition (which is not tuned for nocona, just optimized). The code generation has to be different; this is not a problem on an Intel chip but just possibly it is a problem on the AMD chip.

Try a MinGW-built PortAudio DLL from somewhere?

Regards,
Mike
