Comment (by belegdol):

 byuu (the bsnes author) was kind enough to provide a simple test case. It
 needs some love before it compiles, though.

 {{{
 #include <stdint.h>
 #include <pulse/simple.h>
 #include <pulse/error.h>

 //PulseAudio simple test -- no error handling
 int main() {
   pa_simple *handle;
   pa_sample_spec spec;
   uint32_t buffer[64];

   spec.format   = PA_SAMPLE_S16LE;
   spec.channels = 2;
   spec.rate     = 32000;

   int error = 0;
   handle = pa_simple_new(
     0,                   //default server
     "ruby::pulseaudio",  //application name
     PA_STREAM_PLAYBACK,  //direction
     0,                   //default device
     "audio",             //stream description
     &spec,               //sample format
     0,                   //default channel map
     0,                   //default buffering attributes
     &error               //error code
   );

   while(true) {
     for(unsigned i = 0; i < 64; i++) {
       int16_t sample = sin(i * 2 * M_PI / 64) * 0x2000;  //may need
 tweaking
       buffer[buffer.offset++] = (sample << 16) | sample;  //left and right
     }
     int error = 0;
     pa_simple_write(handle, (const void*)buffer, 64 * sizeof(uint32_t),
 &error);
   }

   pa_simple_flush(handle, &error);
   pa_simple_free(handle);
   return 0;
 }
 }}}
