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?
