GoPro Hero 6 with 5.1 surround microphone

I use PowerDirector 15 when I render this video, and this program has a maximum of 2K 60fps when I want to use Dolby 5.1. After uploading, I am sorry to say that the rear speakers are not active when I play it from CZcams, but it is fantastic when I hear it from the computer. The microphone is a Cascade Audio Vive from B&H.
Does anybody know if its possible to upload with real surround sound? (I'm sorry for speaking Norwegian in this video, but it was not meant to be uploaded).
To hear full surround sound, you have to download - "Last ned" - the video from Jottacloud.no:
