Ashok- > Thanks for your prompt response and suggestion about problem. We have > played sine wave to speaker thru codec and it is working fine. Ok, if you can do that, then you have a good debug start point. Now try to output square wave, then try simple .wav speech file (downloaded through CCS into DSP memory). Maybe you have an issue with sign-extension or left-justification. You s

I have just found (I think) a problem with the TMS320AIC23 codec. If I select the Digital high pass filter (set the control bit to a 1) I am seeing an offset of about -1000 from the codec. If I set this to a 0 it centers itself on 0. This is backwards from what the datasheet reads.
