Missing RIFF chunk

[simoncn]

As I suspected, it sounds like the renderer can't handle the RF64 format. MinimServer is just serving the file "as is" to the renderer, so I don't see what I can do to improve what the renderer is doing.

To confirm what you are saying about Asset and JRiver, do you mean they are accepting the file and trying to play it to the renderer but the renderer is failing? If so, this confirms that it is a renderer issue.

I have successfully played an RF64 file (5.9 GB) from MinimServer to the foobar2000 UPnP renderer. Can you try this as a test?
