Built GNUradio from git on Debian Testing AMD64 this afternoon, and
intending to use it with a Funcube Dongle and gr-fcd. I am having some
difficulty with the ALSA sink and an ICE1712 [M-Audio 2496] sound
card. I created a very simple flow graph with a sine wave Signal
Source straight in to an Audio Sink. When I try to execute it, I get:

I suspect this has nothing to do with ALSA or the ICE1712 driver within
ALSA, since that message comes from the flow-graph executor.
My suspicion is that you typoed at some point in your flow-graph
creation, and created a sink with 10 input ports. From the perspective
of Gnu Radio, one sound-card is the same as another.
