What kind of sound solution is G751 using?

I wanted to know the kind of audio solution G751 laptops use. I saw it said MaxxAudio, but what about Creative software? MaxxAudio does not support positional headphone audio, like Dolby Headphone, Razer Surround, CMSS-3D, or the very best SBX Pro Studio (SBX Surround) AFAIK. This is a gaming laptop, where positional virtual surround sound is quite important! Is there no such software for this laptop? There are 2 types:
1) It takes true 5.1 or 7.1 sound and downmixes it to stereo for headphone...
