Playing wav sound file in Linux in background?

[John Patten]

Hi All...

I've been having a problem playing back an audio file on a Linux  
computer using an "arecord"  a shell script to first create the audio  
file.

The audio file gets created on the local machine, it then gets  
uploaded to an ftp directory, however when I go to play the sound file  
locally using just Rev it's just static white noise.

If I again, use the shell script to play the audio file, "aplay path- 
tofile," it plays fine. However the user can't do anything with my  
stack until the file completely finishes playing.

Is there any way to play the audio file via the shell script in the  
background and still allow the user to interact with the stack?

Thank you!
