Audio files do not play in 0.31.1

[orblivion]

I'm pretty sure I've shared Davros grains to let people listen previously. If I inspect the element, I get:

<audio controls="controls"></audio>

I have a grain with videos, and they play. Inspecting element, I get:

<video src="/dav/filename.mp4" controls="controls"></video>

So the audio source looks like it's not getting set.
