     Unfortunately, while there is a bit that controls sound (on/off) going
to the speaker, many programs ensure that the bit is set to enable sound.
Simply turning off that bit will not always turn off sound.

     Fortunately, there is a PD or shareware, etc. program that can be used
in an attempt to turn off the speaker (via software).  It simply sits in
memory (it is a TSR) and turns off the speaker every time a timer interrupt
comes around (18.2 times a second).  This method works somewhat well; every
time a program tries to make a sound, the sound is cut off at the next
interupt.  In practice, the "sound" turns into a click, as there is sound
for a very short period of time.  Something like this may or may not be
what your friend is looking for.

     If you're interested in it, send Email, and I'll dig the program out
of my archives and mail you a uuencoded .ARC file.
