alice-teacher unable to hear mp3 files

[Don Slater]

This is a known bug in Alice 2.

Sound-related
Alice can play most but not all mp3 and wav files
Open your sound file in an audio editor, such as Audacity, and resave your file as either a .wav or a .mp3. If for some reason the .mp3 still does not work, save the file as a .wav. 

Not all .mp3 files are created equal (created with different codecs and libraries, and it is very difficult for us to keep up with every variation.

Audacity is a free to download and use sound editor. To re-export your sound file as a .mp3 you will have to install the .lame plug-in (as .mp3 is a licensed format), (see the instructions in the Audacity home page (http://audacity.sourceforge.net).

Let us know if you have any questions.

Later,
Don Slater
