Did you cut & paste the code I posted into a New Project and test it as is?

I've used this code several times each time it creates a new file.

If you think about it there is no need for the file to exist, when you pass the Command Method the Open String, it's Opening the Device, not the Wav File, nothing is saved to disk until you send the Save Command.

I'd suggest trying the code I posted again, and perhaps anyone else reading this could try it also and post if it doesn't work.
