new driver

[Benjamin Reed]

I'm attempting to write a driver for MacOSX's CoreAudio for arts, but I'm running into an issue and I'm not sure if it's because I've only got a stub so far, or if it's because the rest of the aRts port has bugs (up until now, arts has basicaly been a no-op on MacOSX, so as long as mcop generally worked, no one would have known there were arts problems...)

Anyways, what I'm getting is this:

---(snip!)---
ranger% artsd -a coreaudio -l0 -f
artsd version is 1.1.0
CoreAudio driver initializing
using device Built-in audio controller for output
32-bit, 44100.000000, 2 channels
audio format is 44100 Hz, 16 bits, 2 channels
addDirectory(/sw/lib/mcop,)
addDirectory(/sw/lib/mcop/Arts,Arts)
addDirectory(/sw/lib/mcop/Arts/Environment,Arts::Environment)
addDirectory(/sw/lib/mcop/Noatun,Noatun)
addDirectory(/Users/ranger/.mcop/trader-cache,)
MCOP ObjectManager: can't find implementation for Arts::MidiManager.
object.cc:1167: failed assertion `skel'
Abort
---(snip!)---

Is this an issue with my audioiocoreaudio.cc stub, or a problem somewhere else in arts/kde? Where should I look to find more? soundserver_impl.cc has some skeleton code for it, but nothing beefy.

Thanks,
Ben
