ADAU1467: SDATA IO several inputs on one port

Hi All,

I have recently made a board that should have the ability to handle 16 inputs in total, on serial port 0 i have one PCM4202 directly attached, and three more modules connected through IO 2,4,6. The primary port alone works perfectly when "Channels/frame and BCLK/channels" is set to 2 channels, 32 bit/channel, now next step is to include the other channels, so i changed "Channels/frame and BCLK/channels" to 4 channels, 32 bit/channel - now it receives data from one channel of each module, so naturally i though this would be fixed by applying 8 channels, 32 bit/channel but doing this bring all channels down except ch 0,1(ch1 gets additional noise in lower region), no data is being received on the others. Disabling IO 4,6 and using only ch 0,1,4,5 also gives the same result in 4 channls, 32 bit/channel mode, only one half of the channels are received. Any ideas or thoughs?
