I have an Edirol UA-25 and it has no software mixer, so I guess the 
UA-1A might not have one as well. I'm using pulseaudio with a simple 
applet for the gnome panel to control the overall system volume, but I 
don't think this will work with mpd. Apparently it might: 
http://mpd.wikia.com/wiki/Features says there's a pulseaudio output 
plugin. Also says it can do software mixing. Hm. Perhaps this does what 
you want, but seems a bit complicated for such a simple task:

Hope this helps,
