Are you trying to play this on Linux or Windows? On Linux, you sometimes
need esd to run be running in order to hear sound in Flash files.

You may want to post URLs to one of the SWFs, maybe the associated .wav
file, and the HTML you use to embed the SWF- I'll then be able to have a look at
where the problem might be.

Yes, wav2swf loads everything into memory before starting to stream it out.
To be honest, I wasn't expecting anyone to convert files that big. :)

Well, you could try to wrap the sound into an .avi file 
somehow (mencoder perhaps, or transcode), and then use avi2swf, which
doesn't buffer so much data.
The other possibility would perhaps be to split the .wav file into chunks,
convert each chunk seperately, and then put them back together with
swfcombine.
