Subject: Fix playing sounds when -soundProgram is empty
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=e3fe733c547d0f8c91c1ff5374a569477a7c1cea;p=xboard.git

Fix playing sounds when -soundProgram is empty

It made no sense to just send the names of the sound files to the shell.
So the soundProgram isnow tested for being an empty string, and if so,
PlaySound() is aborted.
