VigraSound version 1.0 now available (from Vigra):

	IRIS Audio Library software support for
	Onyx/Challenge with VigraSound VME audio board.


Supported platforms:
-------------------

o  IP19 Onyx and Challenge systems
o  must be running IRIX 5.2
o current Audio Library software supports one VigraSound board per host


Software:
--------

o SGI and  Vigra have developed an IRIS Audio  Library driver module and
microcode for Vigra's VigraSound (formerly "MMI-110") audio board.

o  The VigraSound  software  is binary  compatible  with Indigo2,  Indy,
Indigo, 4D/35 audio.

   Any SGI or 3rd party application  which is linked with the IRIS Audio
   Library will  be able to run  on an IP19 system  after the VigraSound
   board and vigrasound software module are installed.

o Collaborative  applications like InPerson, MediaMail,  and the bundled
IRIS media tools will now run with audio on an Onyx (no need to reompile
or relink).

o Onyx/Challenge customers may install the standard IRIS sound and movie
tools  (eg, Audio  Control Panel,  Soundeditor, Movieplayer  ) from  the
dmedia_eoe and dmedia_tools images which are bundled with IRIX 5.2.

o IP19 Onyx/Challenge developers may install the IRIS Audio Library from
the dmedia_dev image  which is included in the IRIS  Media Libraries 2.0
software option product, along with the IRIS Media Libraries Programming
Guide.
