TAudioCaptureDevice WAV format doesn't play backU

I capture a *.wav file using code very similar to the "mobile code snippets audio record play" example. But if I try to open the file I have captured using the Windows Media player it won't play - it reports an error. When I open the file manually and examine it's contents I expect to see "RIFF", file chunk size, "WAVE", file chunk size....... but instead I see "RIFF", file chunk size, "LIST" file chunk size.... The file doesn't seem to contain any chunk of type "WAVE".

Why is there no "WAVE" data?

I am using Firemonkey project, target = Win32, running on C++ Builder Seattle 10 subscription update 1 running on a Win 7 32 bit machine.
