please note that even wine use alsa "default" device does not imply all sound
cards are configured to use dmix

http://git.alsa-project.org/?p=alsa-lib.git;a=blob_plain;f=src/conf/cards/CS46xx.conf


# default with plughw
# CS46xx supports multi-playback

CS46xx.pcm.default {
    @args [ CARD ]
    @args.CARD {
        type string
    }
    type asym
    playback.pcm {
        type plug
        slave.pcm {
            @func concat
            strings [ "hw:" $CARD ]
        }
    }
    capture.pcm {
        type plug
        slave.pcm {
            @func concat
            strings [ "hw:" $CARD ]
        }
    }
}
