I've got the project for wave.c working to the point of being able to call "wave -P 90 FILE.wav" and it will play the 
wav file just fine. However when I try to use waverec.c to create a file and then play it using the "wave -P FILE.wav" 
command, i only get silence. 
I think it has to do with these USB microphones maybe not being supported or a driver not being properly run but I'm not
 quite sure. Any help would be appreciated!
