I'm not sure where to access 'PurePath Wireless Configurator help system'.. is there something online/pdf, or are you referring to installing the program and accessing the help menu within that??
After having looked through the AIC3204 datasheet pretty extensively (and a few others), it only has 8 digital I/O pins; so i don't see how it is going to duplicate an I2S signal [1x4 in, 2x4 out]??
To reiterate, what i want is this:
[digital signal - either USB or I2S] > ??? > [CC85xx and PCM179x simultaneously]
This would be trivial if there was a CC85xx that also passed through the I2S.. surely it is not such a crazy idea for the master to also play the sound! I take it i can't just split the I2S signal lines.
