PortAudio now has WDM-KS

Michael Gogins-2
I'm happy to report that the next Windows installer, Csound 5.15,
which I will upload to SourceForge in the next day or so, will have a
new build of PortAudio with support for WDM-KS drivers (Windows driver
model kernel streaming drivers). These drivers do have low latency,
and most most audio hardware on even moderately new versions of
Windows works with these drivers.

Regards,
Mike

Great! Did you try to build with WASAPI?

Re: PortAudio now has WDM-KS

Michael Gogins-2
It always was, and still is, built with WASAPI. The current built has
drivers for MME, DirectSound (or DirectX), ASIO, WASAPI, and WDMKS.
These are all built with same MinGW compiler I use for Csound.

The problem is stupid and I should have caught it before. There is a
definition of the type of WAVEFORMATEXTENSIBLE in the PortAudio source
code, presumably because it was not defined in earlier MinGW
compilers. That definition now conflicts with the one that is now
defined in the current MinGW compiler. So, I simply removed the
PortAudio definition of this type.

I'm also going to include the pa_devs utility in the WIndows
installer. This prints more complete information about devices that
PortAudio can use than Csound does

Regards,
Mike.

Adam Puckett-2
Thanks Mike! Which version of MinGW did you build WDM-KS support with?
And what's the conflicting definition?
