Your Audio output device and Mixer device are closely tied to each 
other.  If you use an OSS specification for one, you /must/ use an OSS 
specification for the other.  Since you say you're using /dev/dsp above, 
you /must/ use /dev/mixer.  If, however, you use ALSA:default (output 
device), you /must/ use "default" (though, it will allow you to put 
"ALSA:default" for mixer and ignore the "ALSA:" part).

Which shows:

2008-02-09 06:40:21.798 Opening OSS audio device '/dev/dsp'.\
Unable to open mixer: 'default'\

Won't work.

Renderer looks good, though.  :)
