Sony a99 II XAVC-S files no sound in Resolve 11, how to fix?

Resolve 11 can read the video part of XAVC-S but no sound yet. The good news is that the version 12 has added support for this. However, if for whatever reason you won’t upgrade to Resolve 12, you will need to convert your XAVC-S files to ProRes or something similar in order for Resolve to recognize it. You can do this with HD Video Converter. Here’s how.
