 I know mkv compatibility is new in Davinci, that's why I said at the end
 that maybe I will instead convert my webm to mp4 because every software
 recognise those without a problem.

 Yes, changing the extension makes it recognisable for Davinci... The
 video. The sound is still missing.

 I've made more tests and the only files that had this problem were the
 ones I recoded with ffmpeg. I've tried with videos recorded already in
 .mkv and .mp4 files that were recoded to .mkv using HandBrake. All of
 those work, video and sound.

 In fact, I have an idea. I will try to convert the same webm I'm trying to
 make their sound work with Handbrake instead of ffmpeg. Maybe the problem
 is not ffmpeg, maybe it is the recoding from .webm to .mkv.
