XInput won't initialise under Windows 10

[janoi152]

The library is working alright under Windows 7 but when I tried the same application under Windows 10 (v1607) the xinputAvailable was returning false.

I've traced the problem to this line:
@fXIGetDSoundAudioDeviceGUIDS:=getProcAddress(fXInputHandle,'XInputGetDSoundAudioDeviceGuids');
The problem is that this will return nil and therefore the procedure TXInputInterface.initialise will return false.

When I removed all references to fXIGetDSoundAudioDeviceGuids in the unit, the application was working fine for buttons press detection.

I've been investigating a solution since you reported this on PGD. My plan is to implement an OS version check within the initialisation routines, unfortunately it appears that MS have nerfed the version check routines and it's a little more complicated than I had first envisgaed.

Am looking at a solution though.

And is that a universal error (did you successfully replicated it under your Windows 10)? Because it could be something special with my version of OS or other elements.

The simplest option is to attempt to initialise that routine (which from what I can gather is just for headset support) and if it can't, then set a flag in the class to reflect that this particular feature is not available.

In Windows 11 (XInput1_4.dll) i have made following modification to unitXInput.pas:

@fXIGetDSoundAudioDeviceGUIDS:=getProcAddress(fXInputHandle, 'XInputGetDSoundAudioDeviceGuids');
changed to:
@fXIGetDSoundAudioDeviceGUIDS:=getProcAddress(fXInputHandle, 'XInputGetAudioDeviceIds');

so everything looks good for me.
