PMOD i2s2 loopback or pass-thru


Hello. If we use microphone line-in to input voice to pmod i2s2 (with given mclk 22.579MHz , sclk 2.822 MHz and lrck 44kHz) and pass-thru to pmod line out to headphone.

Is it strong enough (our voice) to enable pass thru or loopback ? Tried both but no output from speaker ?
