Raspberry Pi Forums

has anyone managed to get the 'Play[]' function to work on the pi?

I found http://reference.wolfram.com/mathematica/ref/Play.html
So I tried and it chose to give me the 52 definitions of WordData["play"]

When I tried it in a command window I got this: I've not tried transcribing that back into Mathematica.

What you have here is a sound object. Play produces a sound object in Mathematica but EmitSound[] actually plays the sound. Sound is under very active development right now so the playback of waveform audio does not currently function as documented in the initial release. In its current incarnation, it should be able to play certain types of sound if there is a FrontEnd available (i.e. X is running). If you use Speak[] (http://reference.wolfram.com/language/ref/Speak.html) with speakers connected, you should hear speech, for instance. Also, SoundNote[] objects should be able to play from the FrontEnd (MIDI sounds). You should expect waveform audio (EmitSound applied to sound objects produced with Play[]) to work as documented in an update soon.

Hello,
