QEMU uses GUS emulation(GUSEMU32 @url{http://www.deinmeister.de/gusemu/})
by Tibor "TS" Schütz.
Not that, by default, GUS shares IRQ(7) with parallel ports and so
qemu must be told to not have parallel ports to have working GUS
@example
qemu dos.img -soundhw gus -parallel none
@end example
Alternatively:
@example
qemu dos.img -device gus,irq=5
@end example
Or some other unclaimed IRQ.
CS4231A is the chip used in Windows Sound System and GUSMAX products
