I'm not sure this is right. Based on what I was able to glean from
searching the web, there are a couple issues with this:
(1) Depending on how the DAC outputs are wired, using a Y-adapter
on one set of stereo outputs might also cause the other set of stereo
outputs to be mono as well.
(2) At least a basic resistor network (one has already been
described in this thread) is needed to "correctly" sum the two
channels. Now I can't find the link that gave an explanation of why
this is, but my takeaway was that a simple Y-adapter isn't the way to
go.
