  There are two options for audio in an Onyx:

    board per host

    4D/35 audio, and VigraSound audio.

    Any SGI or 3rd party application which is linked with the IRIS Audio
    Library will be able to run on a system that supports the ASO.

  o Onyx/Challenge customers may install the standard IRIS sound
    and movie tools (e.g. Audio Control Panel, Soundeditor,
    Movieplayer) from the dmedia_eoe and dmedia_tools images which are
    bundled with IRIX 5.3 or IRIX 6.0.1.
