Subject RE: sound task - either not doing anything or infinitely looping
Date Sun, 09 Nov 2008 21:03:50 GMT

Thanks for replying; I've updated to the latest driver version of my sound card but no change.
I didn't think the problem would be in that area actually; I have a relatively recent card
I have no audio problems in any other kind of applications. But it was worth a try; appreciate
the response.
I was (and kinda still am) assuming the problem would be more on the Java/Ant side, specifically
something with the buildFinished listener the sound task sets to hook into the end of a build.
Unfortunately -debug doesn't provide any info about that as far as I can tell. 
I guess the only thing I could try is to find out exactly how the task plays the sounds, and
reproduce that in a standalone Java app to (dis)prove the problem is purely inside Ant. If
I get around to doing that I'll post back.
In the meantime, here's hoping someone else has ever stumbled upon the same symptoms and found
the exact cause and/or a solution.

Best regards,

>> I'm getting what I think is very strange behaviour from the sound task. As I understand
it, this is supposed to play sounds at the end of a build, depending on whether the build

does not have any impact at all.

duration it loops forever. As far as I could google and search this and other mailing lists,
no-one else has ever reported this problem. I'm at a complete loss, I think for the first
time ever... on what seemed like a simple and fun icing on the cake of finishing up a script,
and d'oh! :-)
