No audio when transcoding DNXHD/HR files shot on Atomos Shogun Inferno

So I've got a strange problem that's likely to become a bigger headache:

Whenever I try to use AME to transcode from the Avid DNxHD or DNxHR files shot on my Shogun Inferno, the video exports just beautifully, but without audio.

The only way I can get it to export with the audio is to take my individual clips into Premier, and export them through AME as individual sequences, which works, but slows down the workflow when I'm trying to do things like, make smaller files to share with someone who can't handle DNxHR 4K, or make mp4 proxies or reference files for various needs.

I found a few forum entries from older versions, but the solutions listed didn't solve the problem.

Any advice on how to solve this problem? I've got a current workaround, but like I said, its a little slow.

Just to summarize:

I'm using Media Encoder CC 2018

The files are the quicktime .mov files from the Atomos Shogun Inferno recorded with the Avid DNxHD and HR codecs

And I'm trying to transcode them to h.264 or h.265 mp4s to share/store/etc.

Final file exports without throwing any errors, but there's no audio.
