No clue what is going on with your system Steven, but I have yet to have 
the DW gui, in any version, interfere with audio on this ubuntu-10.04.4 LTS 
install.  You may want to look at the gui's config.xml as it probably can 
be changed.  I am not setup ATM with a DW MIDI descriptor in my boot file, 
so perhaps 4.3.0 doesn't acquire an audio device in that event?  Here, 
grepping for /dev/ only shows the ttyUSB1 port I am using for DW.
