Patch for esound 0.2.24 - fixes "-nobeeps"

[Ivan Kozik <ivan xpenguin com>]

Hello,

On a few soundcards, esd -nobeeps sends endless noise. I've searched the
problem on google and usenet, but it was never fixed. The patch I have
attached fixes the problem for esound-0.2.24. On some systems, esd needs
to send some output, or it sends noise continously. I've changed it so
it sends a sound of 0 hz and 0 milliseconds duration if no_beeps is set
to 0.
