Error in analoginput/getdata

I am receiving input from a USB microphone. A loop in my code repeatedly calls

lvl = SLM(AI, Fs, N);

in which there is a line

x = getdata(AI);

that is called.

Everything works fine for the first few iterations of the loop but then I get the following error and warning:

Error using daq.analoginput_winsound_1_127/getdata A timeout occurred during GETDATA.

Error in analoginput/getdata (line 196) varargout{1}=getdata(uddobj,samples,dataformat);

Error in SLM (line 37) x = getdata(AI);

Error event occurred at 12:33:21 for the object: winsound0-AI. A timeout occurred during GETDATA. Warning: Manual trigger with pretrigger before sufficient samples were acquired. Trigger time delayed by 1.#INF seconds.

I'm not sure what is going on here. I would greatly appreciate any help!
