eap0 at pci0 dev 11 function 0: Ensoniq AudioPCI 97 (rev. 0x08)
eap0: interrupting at irq 7
eap0: Crystal CS4297A codec; headphone, 20 bit DAC, 18 bit ADC, Spatializer 3D
audio0 at eap0: full duplex, mmap, independent
midi0 at eap0: AudioPCI MIDI UART

>Description:
	My eap board used to work fine for realplayer and mpg123.
	Then I upgraded my box to -current and I could'nt get any sound
	out of it. mixerctl -a didn't show any difference between working
	and non-working kernels.
>How-To-Repeat:
	Boot -current on a machine with a AudioPCI 97 + CS4297A codec
	(maybe other codecs are different). Try to get noise out of it.
	
>Fix:
	Reverting the following files make it work again:
	ac97.c to 1.15
	ac97reg.h to 1.2
	ac97var.h to 1.2
	eap.c to 1.42
	(all is needed; reverting only the ac97 stuff, or only eap.c isn't
	enouth).
