[PD] portaudio and asio windowz

[Marco Donnarumma]

Ok, now it's working everything fine, thanks for the help.
first Pd 0.42.5 -pa (asio) started recognizing all outputs, but to avoid
clicks I had to use a horrible latency i.e. 190ms... unusable.
thus I've got the "brilliant" idea of ASIO4ALL... (I know.. I could have
thought of it before).

Now I have 16ms delay in Pd and 64 samples ASIO buffer. Works like a
charm...
Asio4All fixed the issue, but I'm curious about the reason why Pd can't
handle properly ASIO by itself (well.... on my machine at least)?
thanks again,

M
