OK, so there are two separate machines? Is the machine that is going to be producing the sound the one that always has the console logged in? Also, are you trying to do any sort of networked pulseaudio setup?

OK, so presumably this means that your machine has pulseaudio set up correctly. Perhaps your issue is that the morse program is not running as your logged-in user, so it cannot connect to your session's pulse socket? --Sean
