static struct mxc_audio_platform_data mx6_sabrelite_audio_data = {

  .ssi_num = 1,

  .src_port = 2,

  .ext_port = 5,

  .init = mx6_sabrelite_sgtl5000_init,

  .hp_gpio = -1,



when I input the :aplay test.wav command in terminal

But no any sound i can heard it So i check the sgtl5000 GPIO .The power 、I2c 、clock is ok. because i can see the right wave in the Oscilloscope !

But i can not see any wave in the I2S GPIO, The I2S RXD GPIO Voltage is high ,the I2S TXD GPIO Voltage is LOW !

Why ?
