It cannot be a sound related problem: xcrysden does not use sound.

Rather, it is a graphics-card related problem. The problem is exactly as
stated above: Togl: couldn't get visual while executing ...

You can try which option makes the "togl" to fail. To do this, you
should execute a simple script like:

# BEGIN SCRIPT
togl .t \
    -rgba           true  \
    -redsize        1     \
    -greensize      1     \
    -bluesize       1     \
    -double         true  \
    -depth          true  \
    -depthsize      1     \
    -accum          true  \
    -accumredsize   1     \
    -accumgreensize 1     \
    -accumbluesize  1     \
    -accumalphasize 1     \
    -alpha          false \
    -alphasize      1     \
    -stencil        false \
    -stencilsize    1     \
    -auxbuffers     0     \
    -overlay        false \
    -stereo         false \
    -time           100

pack .t
# END SCRIPT

Say you put this in file togl.tcl, then do: $XCRYSDEN_TOPDIR/bin/xcrys
togl.tcl
You can, for example, delete the options from bottom to top. By doing
that you will realize which options makes "togl" to fail. Then edit
file: $XCRYSDEN_TOPDIR/Tcl/Viewer.tcl. Search for string "togl" and
remove the problematic option(s).

Let me know your findings ...
