what is the meaning of "This->bufsize_frames" ?


    if(!duration)
        duration = 300000; /* 0.03s */
    This->bufsize_frames = ceil((duration / 10000000.) * fmt->nSamplesPerSec);
    This->local_buffer = HeapAlloc(GetProcessHeap(), 0,
            This->bufsize_frames * fmt->nBlockAlign);






can you add snd_pcm_dump() between snd_pcm_sw_params() and snd_pcm_prepare()




    snd_pcm_uframes_t boundary;
+   snd_output_t *output = NULL;
    const WAVEFORMATEXTENSIBLE *fmtex = (const WAVEFORMATEXTENSIBLE *)fmt;





    if((err = snd_pcm_sw_params(This->pcm_handle, sw_params)) < 0){
        WARN("Unable to set sw params: %d (%s)\n", err, snd_strerror(err));
        hr = E_FAIL;
        goto exit;
    }

+   snd_output_stdio_attach(&output, stdout, 0);
+   if (err == 0) {
+       snd_pcm_dump(This->pcm_handle, output);
+        snd_output_close(output);
+   };

    if((err = snd_pcm_prepare(This->pcm_handle)) < 0){
