SoVRMLAudioClip(3) on Linux
The text 4bc7d75a0121, as Debian 7 (Wheezy) shipped it.
The SoVRMLAudioClip class is used to load and store audio data. Audio data is loaded using the simage library, so make sure you have built the simage library with support for the audio file formats you intend to use (libogg, libvorbis and libvorbisfile for OggVorbis, libsndfile for WAV and several other formats).
