[PD] Trouble enabling full-duplex audio using ALSA

I'm having difficulty enabling simultaneous audio input and output
(full-duplex) under pd.
I can get output to work and I can get input to work but I can't seem
to enable both at the same time. Whenever I try, pd gives an error
message stating "audio I/O stuck... closing audio."
I am running linux 3.6.6 with an M-Audio Fast Track Pro usb sound
card. The pd version is 0.43.4 and I have configured it to use the
ALSA audio API.
As a test, I've managed to get both audio capture and playback running
simultaneously outside of pd by running the following command:
arecord -f dat -D hw:0,1 | aplay -f dat
These above command successfully pipes audio in to audio out, so I can
confirm that full-duplex should be possible with my current hardware.
Can anyone provide some insight?
