Almost there - ALSA - dmix + surround combo

[Gast]

Hi all, I have an Audigy 2 SE soundcard, which uses the ca0106 driver. I've been experimenting a bit with it today, and I can get either dmix working, or surround. However, I fail to get them both working at the same time .
I found a solution that is supposed to work from http://alsa.opensrc.org/index.php?page=DMixPlugin, but it failed for me (error listed below).

Does anyone have anymore suggestions I could try out?

working surround:

Code: [Selecteer]

pcm.snd_card {
   type hw
   card 0
}

ctl.snd_card {
   type hw
   card 0
}

pcm.duppy {
    type route
    slave.pcm "surround51"
    slave.channels 6
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
    ttable.0.4 0.5
    ttable.1.4 0.5
    ttable.2.5 1
}

pcm.!default {
   type plug
   slave.pcm "duppy"
}working dmix:

Code: [Selecteer]

pcm.snd_card {
   type hw
   card 0
}

ctl.snd_card {
   type hw
   card 0
}

pcm.dmix6 {
     type dmix
        ipc_key 1024
        ipc_key_add_uid false # let multiple users share
        ipc_perm 0660 # IPC permissions (octal, default 0600)
        slave {
                pcm snd_card # see below
                rate 48000
                channels 6
                period_time 0
                period_size 1024 # try 2048 against skipping
                buffer_time 0
                buffer_size 8192
        }
}

pcm.!default {
   type plug
   slave.pcm "dmix6"
}not-working surround+dmix:

Code: [Selecteer]

pcm.snd_card {
   type hw
   card 0
}

ctl.snd_card {
   type hw
   card 0
}

pcm.dmix6 {
     type dmix
        ipc_key 1024
        ipc_key_add_uid false # let multiple users share
        ipc_perm 0660 # IPC permissions (octal, default 0600)
        slave {
                pcm snd_card # see below
                rate 48000
                channels 6
                period_time 0
                period_size 1024 # try 2048 against skipping
                buffer_time 0
                buffer_size 8192
        }
}

pcm.ch51dup {
    type route
    slave.pcm "dmix6"
    slave.channels 6
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
    ttable.0.4 0.5
    ttable.1.4 0.5
    ttable.2.5 1
}

pcm.!default {
   type plug
   slave.pcm "ch51dup"
}the error I get:
ALSA lib pcm_params.c:2152:(snd_pcm_hw_refine_slave) Slave PCM not usable
aplay: set_params:874: Broken configuration for this PCM: no configurations available
