I've also noticed this. Does it work when you plug in some headphones? It works 
when I plug in headphones, but 
not through the MacBook's speakers.

I just tried plugging in some headphones and it works then. Is this the way this
program was built to be used or is this a bug? I would love to be able to use it
through my built in speakers as apposed to just headphones.

I think it's a bug. But the author would really know.

I have a 2.0 gig Unibody Macbook and I dont get sound except when I plug in
headphones. So I am assuming the problem has continued. I second the request for
playback through laptop speakers and not headphones!

I have experienced the same problem on an iMac 2.8 GHz Intel Core 2 Duo running 
Mac OS X 10.5.5. Mine also 
works with headphones, but that kind of defeats the purpose. I have experienced 
the same problem with an 
alternative program, Noise UB, except that doesn't work with headphones either.

I have the same problem. No sound through the macbook internal speakers, but it 
will
work both when I use my Creative X-mod for external sound and when I plug in
headphones. (The X-mod is a USB sound device:
http://us.creative.com/products/product.asp?category=209&subcategory=668&product
=15913).
I seem to recall it working the first time I used it, but once I plugged in the 
X-mod
it stopped working through the internal speakers when the X-mod was not plugged 
in. I
could find no setting or plist file that stores the preferred output device so 
I have
no idea if this is a bug in the program or a bug in OS X.

Hello.

I've found fix. Have no idea why it worked using headphones and didn't work 
using
internal speakers.

I had some trouble applying the given patch, so I followed it's changes and
re-created a patch file.  I've also tried to uploaded a new Zip distribution 
that
works with 10.5.7.

Sorry, uploaded my diff in a hurry and realized I had the sizeof operation out 
of
order.  Here's the new diff and binary

Wrong zip.  Here's an updated build.
