Using the quickstart guide:
I am not able to get any audio out of the system. USB to I2C works as I'm able to get the PLL to lock and I see the I2C light on and when it's communicating it blinks, but still no audio output.
I'm not really sure what to try. I have used SigmaStudio 3.17 as well as 4.0 and both behave the same. I am using a standard analog headset mic as the input and the headphones for the same headset for the output.
