4 x ADAU1761 in TDM8

I attached 4 x ADAU1761 to a Blackfin in TDM8 mode, each ADAU1761 must transmit 2 audio channels to the Blackfin. I can configure all ADAU1761 so that they transmit audio on the correct TDM8 channel. The first ADAU1761 uses TDM channel 1&2, the second ADAU1761 uses TDM channel 3&4, .... But the problem is that the first ADAU1761 pulls down TDM channel 3,4,5,6,7&8 instead of beiing high impedance. The second ADAU1761 pulls down channel 1,2,5,6,7&8 and so one. So i am not able to use multiple ADAU1761 on 1 TDM line. Am i configuring something wrong?

 

Thanks
