inaudible output after CoreAudio device initialises+limited number of controls per engine?

hi everyone,

so i am wondering what else i must do after my device successfully completes the CoreAudio initialisation process?

it seems ready to roll:

but when i play something in itunes i don't hear anything. the slider moves as you'd expect.

i compared some properties of the device to the headphone jack and noticed the latter maps to an output device (my headphones). in the case of this sound card, it's just a jack.

is there something simple i'm missing?

lastly, i noticed that the engine is limited to approximately 8 controls. i couldn't add the full 8 channels plus an 'allchannels' volume control, as you can see on the right panel of the second image. this is not due to a programming error.

is it possible that the designers were stingy and used exactly 8 bits to describe the number of each kind of control on an engine (i.e. 8 toggles/8 selectors/8level controls)?

this was my bad lol.

the reason i can't hear anything is because the HDAV1.3 does not have any "powered" outputs. they are all passive (save the HDMI in/out and possibly the mic in).

my bad fellas.
