A table. :)

-soundhw	corresponding -device syntax
---------------------------------------------------------
ac97		-device AC97
adlib		-device adlib
cs4231a		-device cs4231a
es1370		-device ES1370
gus		-device gus
hda		-device intel-hda,id=libxl-intel-hda \
		-device hda-duplex,bus=libxl-intel-hda.0
pcspk		-device isa-pcspk
sb16		-device sb16

(To review it start with "git grep _register_soundhw").
