This may be quite a simple question, but I am a newbie with pure data.

I downloaded this file:
http://puredata.info/groups/pd-graz/workshop/20070309/pd-audio.zip/view?searchterm=audio
But when I connect my .wav file by pressing the blue button which is on my desktop and press the red playback button nothing happens.

Here are my audio settings: http://i45.tinypic.com/4ub3o0.png

Do you know what went wrong or are there some other settings I should check?

Regards,
Anna

Thank you both very much for answering so quickly.
I'm sorry for posting in the wrong section.
Yes, I talk about the D2.playing_back_a_table patch, sorry again for not mentioning.

I did a screenshot for you, because I think I still fixed compute audio and there's still no sound. (And yes, the speakers of the laptop are switched on too..... .. )
