Great to hear about the HRTF. I'll probably switch from the openal-mob fork to the latest openal-soft.
Not sure, but i don't think you can directly initialize it like that. I just switched the arrays to being initialized normally inside the constructor body.
alure\src\source.cpp(371): error C2057: expected constant expression
if(processed > 0)
{
ALuint bufs[processed]; // errored line
alSourceUnqueueBuffers(mId, processed, bufs);
}
Even if you were able to initialize a variable size array like that, won't this just pass an array of uninitialized/invalid buffer IDs? If so, where are the list of processed buffers stored? Line 397 also has this as well.
source\alure\src\decoders\sndfile1.cpp(19): error 2666: 'std::fpos<_Mbstatet>::operator !=' : 2 overloads have similar conversions

Yes, if the device is configured as headphones. More specifically, if PKEY_AudioEndpoint_FormFactor gives back 'Headphones' in mmdevapi, or IDirectSound::GetSpeakerConfig gives back DSSPEAKER_HEADPHONE in dsound.

This looks like it's having trouble with C++11. Or my C++11 is wrong.
The code in question is:
class Vector3 {
ALfloat mValue[3];
...
Vector3(ALfloat val) : mValue{val, val, val}
{ }
...
};
As far as I know, this is a valid way to initialize arrays in C++11. Or isn't it?
