Hi Dennis!
I could be wrong, but first you have to set all pipelines, then use interleave element to interleave streams and then sink it to alsasrc of device for your device which takes in all channels. For that you have to use direct access to ALSA (without Pulseaudio). Peteris.

Hi Dennis again!
If you access ALSA devices directly, you should know in what format they accept audio data. As you can't know for each device you use ALSA provides plugin, which is used in 'plughw:1,0' format (I think, haven't touched ALSA recently). It automatically resamples data to format accepted by device. Also using 'default' device ensures that you give device right format for data. In ALSA wiki there is more about how to use device addresing and plugins afair. Peteris.
