Comment (by PassingStrike):

 I checked my files (the ones that work in Davinci and the one that
 doesn't) with ffprobe ('''ffprobe -i input''') and I found a key
 difference in the audio stream:

 Original .webm:
 {{{
 Stream #0:1(eng): Audio: opus, 48000 Hz, stereo, fltp (default)
     Metadata:
       DURATION        : 00:03:08.021000000
 }}}
 Mkv encoded with ffmpeg:

 {{{
 Stream #0:1(eng): Audio: vorbis, 48000 Hz, stereo, fltp (default)
     Metadata:
       ENCODER         : Lavc60.4.100 libvorbis
       DURATION        : 00:03:08.008000000
 }}}

 Mkv encoded with Handbrake:
 {{{
  Stream #0:1(eng): Audio: aac (LC), 48000 Hz, stereo, fltp (default)
     Metadata:
       title           : Stereo
       DURATION        : 00:03:08.010000000
 }}}

 Original mkv:
 {{{
 Stream #0:1: Audio: aac (LC), 44100 Hz, stereo, fltp (default)
     Metadata:
       DURATION        : 00:03:57,493000000
 }}}

 As you can see, any .mkv that works has aac as the audio format, while the
 others do not. Maybe Davinci doesn't recognise opus or vorbis, and that's
 why it doesn't recognise the audio.
