Hi ajax - I'm a bit confused
Hi ajax - I'm a bit confused at what exactly your friend is trying to
accomplish. I'm sure it's something very neat but right now I'm lost
:~)

To answer the question about the iPad outputting digital audio -> The
headphone jack is only analog. But the dock connector can output
digital audio with the camera connection kit. You can only connect to
a 16 bit USB DAC, but at least it's digital out. A good 16 bit DAC for
this is the Devilsound / Halide Design DAC."

But I stand corrected on one count: the Alesis ioDock does not appear
to do ANY conversion. While the 30-pin connector DOES carry a digital
audio signal (that's what makes it possible to use an HDMI connection
to have Hi-Def A/V) apparently the ioDock is using ONLY the analog
audio signal. Still haven't' found a definitive answer/source for
that, but that's the conclusion I'm getting to on what I'm finding.

I suppose that technically you could grab the digital signal off the
right pins if you knew how to design the hardware & software to do
it…that's a bit beyond me, tho'!

Best,
