I would recommend that you make your minimum supported release 10.2.8.
Nobody should running releases earlier than that: There are many
serious bugs. And not just Core audio bugs. If I remember correctly,
there were also a lot of Firewire and USB problems.
Hi Herbie -
Well, ya got MY vote... but, it never amazes to cease me how people
will cling tenaciously to the older versions of the OS - and that's not
quite so surprising when you consider how 40-to-100MB OS updates are
essentially impossible over a dial-up connection - which is still the
reality for many.
One difference I DID notice about the 10.2.3 world of audio is that
the invention of the 'AudioConverterFillComplexBuffer' function had not
yet occurred. The implication being that I need to create and invoke a
completely separate audio playback capability if it is determined the
OS is less than 10.2.something. For sure, the Mac was playing music in
10.2.3 - so we know it IS possible - only it's now done differently
than it was then.
I'm going to give it a go - try to conditionally execute based on OS -
using the API from the 10.2.3 AudioToolbox when appropriate. It looks
like the main areas involved are the buffer definition and the render
function. It'll never be THAT simple... but you gotta start somewhere.
Best Wishes - and thanks for your input,
Lance
