hello all
we have a problem with the mcasp and codec audio.
We try to generate in the dsp, a dc signal (constant) to send to output line in the codec audio using mcasp. When we try to recover the constant (interconnect a cable from the output to the input audio codec), this signal are not constant.
our program are attached and the output is like that:

what is wrong? The configuration to mcasp's registers are wrong?
