Hi,
What is the source of this compressed stream? DVD player?
Are you using the ADSP-21489 EZ-Kit? I would recommend you to run the SPDIF to Analog Talkthru Example code provided in the VDSP++ Installation Directory .It has all the SPORT ,SRU and SPDIF configuration. You can also use this project as a reference for your code
