I need connect imx6ull cpu to external audio-codec w681310 (PCM, I2S) and GSM-module with PCM audio (for example SIMcom SIM5360E).
If i route audio from GSM-module to internal SSI1 port (host port 1) (for record, and mix audio) can i simultaneously route audio after mixing through internal SSI2 port to audio-codec?
GSM(PCM)->PP1(SSI1)->AUDMUX->HP1(SSI1)->CPU(mixing, record audio)->HP2(SSI2)->AUDMUX->PP2(SSI2)->codec(PCM)
Or i can use only one internal SSI port for record, mixing and routing audio?
GSM(PCM)->PP1(SSI1)->AUDMUX->HP1(SSI1)->CPU(mixing, record audio)->HP1(SSI1)->AUDMUX->PP2(SSI2)->codec(PCM)
