Exact steps for others to reproduce the error

  • Extract files. Audio is an external file because I can't reproduce the bug if it's packed to .blend.

  • Go straight to "Render" -> "Render Audio"
  • You should hear that in exported audio file the music stops after the first strip ends.

Bug seems to have something to do with keyframed volume in the second strip.
