Hi, Does anyone have or know if there's a sample DSP loopback program that samples the AIC33 mic input (like say 8Khz, mono, 16-bit) and then plays it through the AIC33 headphone output? I know I can do this on the ARM side by accessing the /dev/dsp device, but I need to access the mic input and headphone output directly from the DSP side. Basically, I want to create a DSP codec that reads from AIC33 mic input and sends the data to the ARM side (via CE API) and vice versa: gets data from the ARM side and writes it to the AIC33 headphone output. I looked at the encode/decode examples in the DVSDK but still don't know how to access ore make use of the AIC33. Sorry, I'm very new to the TI DSP development environment and don't know much; I spent the last week just learning about xDAIS and DSP/BIOS by going through the CCS 3.2 tutorial. Your help is much appreciated. Thanks.
