Try the TI SN76489A, or its equivalent by NCR - the 8489. The IC
provides three tone generators, a noise generator, four programmable
attenuators and a mixer. It's a nice IC for microprocessor control (for
all intents and purposes it cannot be used on a standalone basis).
I don't have a pricelist handy, but small quantity pricing should
still be less than $ 5.00.
