I've used this mips CPU myself for Linux projects (actually the AU1100).
The audio driver is OSS based. Unfortunately the CPU does not have a
floating point unit. FluidSynth uses floating point rather heavily, so
it will most likely not run with any usable performance (due to FPU
emulation overhead). I believe at one time Peter Hanappe or Markus
Nentwig converted FluidSynth to using integer math as a test. I'm not
sure what the state of this is though. I am also interested in getting
FluidSynth running on my mips AU1100.

Does Peter or Markus have any information on using FluidSynth with
integer math? It would be a cool feature for embedded FPU-less systems.

Hmm, not sure what is causing those problems. I would think the OSS
driver should theoretically work. Regards,
