Hi, I want to capture input from the line in input on the board and convert it to digital for processing on FPGA without Nios II. The examples on the CD weren't helpful. i2sound example bypa...

Honored ContributorI don't see a clear preference for master or slave mode, both can work. The i2c_sound demonstration runs the Codec in master mode, but as you said, it's not processing the data or clock at all, just performs an ADC to DAC loopback.
To record or sendout data, you need shift registers, clocked by BCLK and captured/loaded on LRC (frame clock) edges. Unfortunately, no demonstration is provided for this basically simple process.
