Hi.  I've built a small application using JBuilder 2.5K.  Under a certain circumstance the program executes a beep command. This runs fine from the pc I'm developing it on -- either from running in the IDE or from a executable jar.  However when I copy the jar to another pc the beep no longer works. The other parts of the app. do work -- textBox, dialogs, ....  Any insight as to what's missing or wrong with the other systems?

How exactly does it "execute a beep command"? Are you calling 
Toolkit.getDefaultToolkit().beep()?

I suspect this depends on a PC speaker setup (i.e. not using regular 
sound-card sounds). Perhaps your other PC doesn't have a built-in PC 
speaker?

Try opening a CMD window, and executing "echo ^G" from there (by "^G" I 
mean "Control-G"). If you don't get a beep, start by debugging that 
problem first..

Shankar, thank you for your response. Yes, the call is as you suggest -- "Toolkit.getDefaultToolkit().beep();".  Both systems, mine and the problem one will perform a sound through the PC Speaker when cntl-G is entered at the command line.  The program when run on my PC makes the beep through the sound card not the PC Speaker.  Also the problem PC will play a streamed audio from the web -- so I beleive the sound card is working in the problem PC.  Any other thoughts?  --- Mike

Good debugging info. Alas, I'm fresh out of ideas now..
