I don't understand the question : what are you expecting to see?
The audio HAL shows one synchronized built-in controller for
input/output.
If you want to select the input port (like internal microphone, external
microphone and so on), there you can use the selector for internal input
on that HAL device (or higher level API like Carbon Sound Manager).
But physically there is only one "Built-in controller" shich corresponds
to
the Codedc inside the machine. The connections are all ports on that
same Codec,
and there is only one input and one output stream that goes from/to the
Codec
to tha macio controller. Physically you have only 2 DMA engines (one for
input one
for output) that are synchronized and presented as one synchronized I/O
engine
in the HAL (in 10.1)

Any news of the 'Built-in Audio Controller' action? I still cant see my
internal mic, or any internal hardware as anything but an over all
'Built-in
Audio Controller'. I just tried it under 10.1 and I get the same thing.
Same
with QTJava. Is there another way of connecting to internal devices for
recording?
