Apologies for leading you down a dead-end. I've taken a closer look
at the code and found what the problem is. The pacat-simple.c example is
expecting raw PCM sample data in the file. Since you're giving it a .WAV
file, there is a metadata header at the beginning that it is trying to
interpret as audio.

Try inserting this line just above the /* Read some data ... */ line:

read(STDIN_FILENO, buf, 44); // Discard the .WAV header
