Blender 2.80 8ac0fef4df 2019-06-14 does not render speakers' sounds at all even though I have enabled sounds in the audio panel in the scene's properties.

Exact steps for others to reproduce the error

Create an animation, it can be a simple move of a cube from point A to point B.
Add speaker to the viewport and attach sound.
Render the animation as PNG pictures.
Open Video Sequencer
Add rendered PNG pictures as Image Sequence
Switch Output file format to FFmpeg Video and choose any settings for video and sounds
Render the animation

The result? The animation does not have sounds played by speakers.

Probably similar issue as to #65814 (I haven't tried to reproduce this though).

@dfelinto, this is a totally different issue.

Developer note.

Part of the issue here is that speakers were not in the dependency graph in this configuration. The attached patch fixes this aspect.

This makes dependency graph and evaluation do the right thing judging by the logs. However, this isn't enough to get the sound in the final video. Could be that sequencer rendering and video output are using different sound handles or so.
