Hi, I'm looking for a simple example about how to use the DSP processor C6748 of my OMAP L138 for AUDIO issues. Since I would like to work in real-time, which codec do I need? I would appreciate an example about which codev to use and how to initialize it for the purpose. I can't find any template available. Thanks for helping.

Francesco,
A simple audio example is included in the BIOS PSP of the platform. You can download the BIOS PSP for OMAPL138 from here:
http://software-dl.ti.com/dsps/dsps_registered_sw/sdo_sb/targetcontent/psp/bios_psp/index.html
Under pspdrivers_xx_xx_xx\packages\ti\pspiom\examples\evmOMAPL138\audio, you should find an implementation of the sample application for the demonstration to play audio through the audio interface layer.
If you are looking for an ARM+DSP SoC example, you can find that in the DVSDK kit for the platform. This is a little more complex example that uses DSPLINK layer to program the DSP from the ARM. Details of this implementation can be found on this wiki:
http://processors.wiki.ti.com/index.php/Audio_Soc_example
For recommendations regarding audio codecs refer to the OMAPL138 Complementary Product recommendations mentioned here:

Hope this helps.
Best Regards,
Rahul
