For SPARC users:

Mxv will convert sounds on SPARC 1+, 2, LX, 5, 10, and 20 machines.  

For the LX and 10, you *MUST* add the following to your environment:

setenv MXV_SPARC_10 YES

and for SPARC 5's and 20's:

setenv MXV_SPARC_20 YES

...or else sounds will not play and record properly.


SPECIAL NOTE:

On SPARC5's and SPARC20's, the audio system software has a bug which truncates
sound playback to the largest .1-second multiple of the selection.  There is
an official patch available from Sun to fix this.  Here is the relevant
information:
