I'm having some trouble using pocketsphinx. I'm running Fedora 9 on a Dell Latitude D630 and I know the built-in microphone is fine, as I can test it in the sound preferences as well as using `arecord`. I get the following output from pocketsphinx_continuous:

The "Input overrrun" messages continue until I exit manually. I don't have ALSA, pulseadio or esd running.
I'm using sphinxbase 0.4.1 with sphinxbase 0.5.1 and am very new to all this. I'm thinking there must be a configuration file where I define my mic hardware, but I can't seem to find anything on it, and Google is entirely unhelpful.
