Actually, i do think it has a dependency hell and it's archeteture
is just insane.  I couldn't pull it apart to debug it, so I just
scrapped it and used ALSA straight up.  And at least in OpenSuse it
won't work without gnome.

The main thing I understnad about it is that it can serve sound from one
desktop to another.  Fine.  But its not worth the cost.  the hell with
it.  I'll run an icecast server.

You must be a stupid engineer then, because politcs and technology have been attached at the hip since the 1st dynasty in Ancient Egypt.  I guess you missed that one."
