Jack always tries to use the same sample format for both playback and
capture.

Try this:

pcm.emi62 {
	type hw
	card 0    # or whatever it is
}

pcm.emi_all_24 {
	type asym
	playback.pcm {
		type linear
		slave {
			pcm emi62
			format S16_LE
		}
	}
	capture.pcm emi62
}

ctl.emi_all_24 {
	type hw
	card 0
}
