Sortie analogique et optique en même temps

Bonjour à tous,
j'essaie de faire marcher ma Terratec 7.1 space à la fois en analogique et en optique
pour sortir le son sur mon ampli et sur les enceintes stéréo de mon TFT.

aplay -l

tazman@tazland-ubuntu:~$ aplay -l

voici le contenu de mon asound.conf

# Override the default output used by ALSA.
# If you do not override the default, your default
# device is identical to the (unmixed) analog device
# shown below. If you prefer mixed and/or digital
# output, uncomment the appropriate four lines below
# (only one slave.pcm line).
pcm.!default {
	type plug
		## Uncomment the following to use mixed analog by default
	slave.pcm "dmix-analog"
		## Uncomment the following to use mixed digital by default
	#slave.pcm "dmix-digital"
}

# Direct software mixing plugin for analog output on
# the nForce2/4 (hw:0,0)
# Do not use this directly--it requires specific rate,
# channels, and format

	ipc_key 1234
	slave {
		pcm "hw:0,0"
		period_time 0

# Direct software mixing plugin for digital (S/PDIF) output
# on the nForce2/4 (hw:0,2)
# Do not use this directly--it requires specific rate,
# channels, and format
pcm.dmix-digital {
	type dmix
	ipc_key 1235
	slave {
		pcm "hw:0,1"
		period_time 0
		period_size 2048
		buffer_size 32768
		periods 128
		rate 48000
		}
	}

pcm.mixin {
        type dsnoop
        ipc_key 5978293	# must be unique for all dmix plugins!!!!
        ipc_key_add_uid yes
        slave {
                pcm "dmix-digital"
		period_time 0
		period_size 2048
		buffer_size 32768
		periods 128
		rate 48000
        }
        bindings {
                0 0
                0 1
        }
    }

pcm.duplex {
        type asym
        playback.pcm "dmix-analog"
	capture.pcm "dmix-digital"
}

La sorte analogique marche avec dmix-analog,
la sortie optique marche avec dmix-digital dans le "pcm.!default".

Comment faire pour avoir les 2 sorties en même temps
