MPV and ffmpeg build just fine. However, as per https://github.com/mpv-player/mpv/issues/13662, the current build of mpv does not support audio output due to an incompatibility that 0.36 has with current ffmpeg. The error you get is as documented in the issue, but is also presented below:
PS D:\Videos> mpv '.\test.mkv'

Moving to master rather than 0.36.0 seems the best long-term solution. In the very short term you can add do_patch "https://github.com/mpv-player/mpv/commit/f31eb9e4071093134d675678d29e8f1673d39d18.patch" am to the media-suite_compile.sh and it does fix the problem.
