Hi,

FWIW I have the same problem, and I’ve also found that audio is not output when rendering animation to a video file. (The created video has no audio)

System: Windows 8.1, 64bit
Blender version: 2.91.0 Alpha

Thanks
Will

@William Alexander (willalexander) Yes, that would have affected any kind of strips producing sound...
