Hi,

the Play function produces the interface on which you have to click to play the sound. If you want to play the sound directly you can use:

EmitSound[Play[Sin[440 2 Pi t], {t, 0, 1}]]

Cheers,

Marco

Try your example again. Play[Sin[440 2 Pi t], {t, 0, 1}] should work now. There was indeed a bug with the click handling. We recently improved support for this. We have not yet removed the "not supported in the cloud" icon in the documentation.

Thanks,

John

Oh, now I see what you are saying. Sorry. Yes, it does work for me. (OS X 10.10.4, MMA 9-10.2). Never had a problem with it.

On Programming Cloud in a browser?

Do other interactive boxes work on your computer, e.g. does Manipulate work as expected? Which version of Mathematica

Not Mathematica. Programming Cloud.

I guess that this is not a problem specific to Play. Can you play any wav-file after importing it?

As I said, the docs Play example works fine.

the Play function produces the interface on which you have to click to play the sound.

Understood. Does it work for you?

Because, as I said, when I click ">", I just get the border shown.
