Short description of error

In the attached blend file, I have two notes playing simultaneously, with fades applied from blender.
If I render the scene called "scene", one note fades in and the other fades out, which is what I want.

The problem comes when I try to place a scene strip in another scene (the one called SceneRef here).
This scene sounds correct when I play it in the VSE, but when I actually render it, only one of the notes is played, and there is no fading.

Exact steps for others to reproduce the error
Play the attached blend file, or:

create a scene with two audio strips
have output format set to ffmpeg / matroska / with audio = aac
have one fade in and other fade out.
add that scene as a scene strip in a second scene (using same output settings)
render the second scene

Can you provide hardware information. Including the system-info.txt generated from the Help > Save System Info Menu will give information about the OS, hardware, drivers, Blender version and add-ons enabled.
