gstreamer can not play .wav filr to usb audio device

Hi,

after tracing the wavparse code,
the error is caused by
gst_wavparse_stream_data (GstWavParse * wav)
about line 1997, gst_pad_push get error,

  if ((res = gst_pad_push (wav->srcpad, buf)) != GST_FLOW_OK)
    goto push_error;

Does anyone have idea about how to debug this kind of error?
Why USB Audio device cause this kind of error?
Because When I test the same audio file via I2S device, it is OK,
It is fail when I change to USB Audio device.
Anyone have idea?
