Actually looking at the code in alsa-sink.c the default device is not 
"default" which seems like it's asking for trouble if alsa is routed to 
PA :s

The wiki is actually pretty out of date overall with regards to module 
documentation... I wonder if we can do something code based to 
automatically update it (e.g. generate the wiki docs from the doxygen 
docs in some capacity...) Hmmmmm
