MacBook built-in sound + JACK: possible?

[Paul DeShaw]

Greetings,

Although I have a USB interface, sometimes I like to do a little editing or
scratchpad recording directly into the laptop, without bulky equipment and
associated cords and power supplies.  I have experimented with it, and so
far, I can record in Ardour, but I can't play anything back.  In JACK I
choose either HDA Intel or STAC92xx Analog for the input and output
devices.  The meters bounce, and the routing in the Connect window looks
fine, but I can't hear anything.  I can get sound out of this card with
non-JACK audio apps, so I know it works.  Is there anything more I can do?
