I suspect that there are two problems, one easy and the other yet unidentified.
If you set VOLUME to 64 in vt100.h and compile under Manx, then setting
VOLUME to 0 in vt100.init produces neither sound nor flash.  But if you set
VOLUME to 0 in vt100.h under Manx, then set VOLUME to 64 in vt100.init,
you get sound, or if you set VOLUME to 0 in vt100.init, you get the flash
like you're supposed to.  That's the easy one.

However, I have heard numerous complaints from otherwise generally competent
individuals using Lattice that they couldn't get sound or flash, which leaves
me to suspect that Lattice is doing something different than Manx.  There was
a net article dealing with compiling VT100 under Lattice (1574@jade.BERKLEY.EDU)
by Mike Meyer; it contained a Fred Fish style makefile.  He said that all he
did was "I twiddled the MANX and LATTICE defines to 0 and 1 (respectively)
in vt100.h"  He then made some changes to the code regarding screen placement.
(He was working with v2.2, which had some problems that were fixed in v2.3.)
Other than that,  I don't recall ever seeing an article showing changes to
the code to fix a possible Lattice no-sound syndrome.
