So recently got My GoPro Hero 6 and I've run into a interesting issue. I can import the files as normal but after I've let Vegas 15 build the peaks it I try to preview the footage. The audio is just a bunch of noise/crackling. The video format is the new hevc format GoPro has for their 4k 60FPS recording. The video is fine except its difficult for the preview window to keep up (this is normal for the most part). it's just the audio that I can't live or work with.
