Again, going on this nomenclature -- to my knowledge aRts is the only sound 
server that does decoding.  MAS may do that too, not really sure.  But most 
"sound servers" are basically just a system for mixing stuff and forwarding 
it to the hardware.  I think that's what Guillaume and Alex are arguing 
against -- when that's all the soundserver does there are cases where you 
don't need one.

Again, sound servers don't usually decode stuff, and what the guys on 
core-devel were suggesting was something that handles the decoding...

Just for a little bit of background -- at least for GNOME GStreamer will be 
that layer (and I'm interested in other similar frameworks as well...).  It 
handles encoding, decoding and effects (which to an extent are needed -- 
think volume, video brightness, etc.)  If we decide to add something KDE 
specific to do that I just feel like we're getting back into something that 
will be both incomplete and likely poorly maintained.  But hopefully we'll 
hash some of that stuff out shortly...

Not really interested myself, but sure, fine go for it.  Just decouple it from 
the simpler parts.
