Exec problem

[JediDan]

Trying to use the Linux SoX program through PHP. Just as a test, I'm doing:

print exec('play /home/dan/Beep.wav');

This works fine from the command line, but I get absolutely no response or results when running it inside of PHP. I can do "play --version" however, and get the correct results.

Any ideas?

Any help is appreciated.

Thanks,

Dan
