TMS320C5515: TMDX5515EZDSP REV D Microphone issue

Part Number: TMS320C5515
Other Parts Discussed in Thread: TMDX5515EZDSP

I have purchased TMDX5515EZDSP REV D Board. I tried aic3204 test but something is wrong with the second part of the test: aic3204_loop_stereo_in1() function.

It seems that there are some non-zero values read on 'data3' and 'data4' variables(also if i don't speak on the mic), but there is no sound that can be heard on the speakers:

data3 = -120
data4 = -132
data3 = -117
data4 = -130
data3 = -115
data4 = -128
data3 = -116
data4 = -128
data3 = -115
data4 = -126
data3 = -114
data4 = -126
data3 = -114
data4 = -126


I use a Wimitech CS-1005 headphone with integrated microphone.

Is there any software patch on the aic3204_loop_stereo_in1() function?

Thanks in advance

Best Regards,

Paolo
