PCM1863 EVM Issue

I am trying to record voice using the PCM1863 EVM with two microphones. I connect to the EVM with PurePath 2.1 on my PC but it says the EVM is connected as PCM1865. An FAE told me it’s because the PCM1863 plugin is missing. Anyway I could only download this tool on the website. So I placed the jumpers, set up the analog inputs and recorded obviously nothing but noise. Holding down the PCM9211 reset button (white one) takes out the noise. It makes me think the signal I got was from the optical in and analog is not being sent. I suspect the EVM is in Mode 0 described in the datasheet. What I don’t understand is both without the Y0 and with J8, J9 and J11 in place how the board tells if I want Mode 0 or Mode 2. Is there anything else I need to set to acquire analog signal and disable the optical inputs?

Hi Sir,

Please help to try the step by step as enclosed documents. Thanks!
