in init() there is

   alGetBufferi(buffers[0][0], AL_FREQUENCY, &bufrate);
   ao_data.samplerate = rate = bufrate;

call to alGetBufferi before alBufferData is useless...?

it should be

@@ -103,7 +110,7 @@
      alSource3f(sources[0], AL_POSITION, 0, 0, 1);
    ao_data.channels = channels;
    alGetBufferi(buffers[0][0], AL_FREQUENCY, &bufrate);
-  ao_data.samplerate = rate = bufrate;
+  ao_data.samplerate = rate;
    ao_data.format = AF_FORMAT_S16_NE;
    ao_data.bps = channels * rate * 2;
    ao_data.buffersize = CHUNK_SIZE * NUM_BUF;
