Texas Instruments used to make the SN76477 and the SN76496.
These are listed as "sound generators" and were meant to be
used in video games to produce a variety of sound effects. They
contained a noise source and various envelope generators.
The former chip (and maybe the latter) are no longer made, but the
data sheets may be available somewhere. They showed how various
sounds were synthesized; this might give you some ideas.
