TLV320AIC3101 (i2s) parallel with 2 master (CC8531)

Hello.

I need to use 6 slave (using CC8531) and as I know this IC can have maximum 4 slave. 

So I would like to know, is it possible to use two master (cc8531) that have same audio source (from codec TLV320AI)?

I already tried to connect BCLK, WCLK, DOUT, SCL, SDA, and RESET pin from TLV320AIC3101 (codec) to 2 master (CC8531). But it seems that audio came out from each slave have ripple noise.   

It seems like i2s data is corrupted. so can i2s communication in parallel mode?

    If the I2S is configured correctly, you should get perfect audio - even from two channels in parallel. There must be something else going on.

    We would need much more application detail (schematics, scope shots, fft's, etc...) to offer any useful guidance.

    Specific question on the CC device would have to go on the wireless forum.

    Best Regards,
