Hi, I'm am working on C5535 ezDSP KIT, and i want to record voice by Stereo in and test it through Stereo out on KIT, I used the sample of TI. But i can't listen anything. Please someone heps me how to fix it. I'm very glad to get your advices. Here is my source. Thank you!

/* Initialise the AIC3204 codec */
aic3204_init();
/* New. Default to XF LED off */
asm(" bclr XF");
for ( i = 0 ; i < SAMPLES_PER_SECOND * 600L ;i++ )
{
aic3204_codec_read(&left_input, &right_input); // Configured for one interrupt per two channels.
mono_input = stereo_to_mono(left_input, right_input);
left_output = left_input; // Straight trough. No processing.
right_output = right_input;
aic3204_codec_write(left_output, right_output);
}
/* Disable I2S and put codec into reset */
aic3204_disable();
printf( "\n***Program has Terminated***\n" );
SW_BREAKPOINT;
}
