Difficults to create sound notifications

Dear,

We're trying to create a sound alarm on Opmanager, but it doesn't work.
We create a "Run program" calling java to execute the audio file, but it doesn't work.

We used the follow command:
Command name: ./jre/bin/java
Program attributes: -classpath ./classes/OpManagerServerClasses.jar com.adventnet.me.opmanager.server.alert.AudioNotifier ./conf/application/scripts/MySoundFile.wav

PS:
We wish play the sound on client web navigator (remotely)
If we call the command above in a MSDOS using Java command the sound is played normally (On Opmanager server).
Web Alarm runs the sound ok (on client web navigator)

Our system details:

OS Name & Version : Microsoft Windows Server 2012 R2 Standard
OpManager version : 11600 (64 Bit)

Hope someone may help me.
Best regards,

Diego Pedroso
