Hi Stan thanks for helping out.

In the original mail I attached my asoundrc setup it can also be found 
here: http://debian.pastebin.com/m52601230 and now here below.

pcm.!default {
    type plug
    slave.pcm dmixer
}
pcm.dmixer {
    type dmix
    ipc_key 1024
    slave.pcm hw:audiodevice0
}
ctl.!default {
     type hw
     card audiodevice0
}
ctl.dmixer {
    type hw
    card audiodevice0
}
pcm.dsp {
     type plug
     slave.pcm dmixer
}
ctl.mixer {
     type hw
     card audiodevice0
}

I am no asourdrc specialist and I always have got issues understanding 
the syntax when it comes down to more complicated setups. I know I need 
to make the audiodevice0 the default device. But how can I do this 
without losing my mixing support, how I configure it so it has dmix and 
dsnoop as default devices?

An example how to fix my asoundrc would be really helpful.

Thanks in advance,

Jelle
