Hi Folks,
I'm doing playback through an AU graph consisting of a format
converter, stereo mixer, a custom volume unit I wrote, and the output
unit. Instead of the older Component Manager calls, I'm putting it all
together via AUGraphAddNode(), AuGraphConnectNodeInput(), &
AUGraphNodeInfo(). It all works fine until I add a graphic EQ unit
into the mix, and then I get no output. The graph pulls from my input
callback, but nothing out the speakers. The EQ unit appears to load
and get connected just fine, stream formats set okay, I can even set
the 10/31 band property, get the property labels back and see how they
change, all with no errors returned. I'm not instantiating the UI, but
was planning to control it through properties.
Is there some other initialization this unit needs, besides what can
be gleaned from the header files, or via auval? Are there limitations
as to what it can plugged in to? Is there something else I'm missing?
Clue is appreciated.
thanks - dmt
