recorded audio from microphone and then saving it as a wav file except the wav file increases in size but there is no audio in the file at all?

I have the same problem but I KNOW that the problem is not in the audio card but in the file format.

If you laback the file with labview functions, you willl heard all sound you recorded.

You can not heard the sound by a media player.

Maybe that's beacause labview save wav file in a non standard format.

I'm going to contact national instrument support to find out what's wrong with the format.
