I'm also working on trying to get this working and I'd be very interested in advice or if possible sample code that demonstrates how to do that.
I'm currently trying to use two Audio Queues, one for offline rendering and one for playback, instead of using RemoteIO, so I'd also like to know if one method should be preferred over the other and why.

Thanks!
Hugo

I finally got to the point where I have Audio Queue Services offline
rendering a buffer and core audio remoteIO playing the PCM data behind
it.  However, for some reason I'm noticing that some files are
decoding faster than others and it's really throwing a huge problem in
my timing.  Too slow and the latency becomes a problem, too fast and
well, we all know what happens then.  Getting this is proving to be a
real balancing act and this is before worrying about interruptions and
their speed associated with their callbacks.
Out of curiosity, has anyone managed to get that type of pipeline
working?  Anyone have any good ideas for how to solve the timing
issues I'm having as I'm currently drawing a blank.  Thanks all!


Thanks,
Steve
