SIGMA STUDIO FIRST PROJECT

i made this project , simple volume control and generated files by link , compile, download. . then using codes integrated this to existing processor code having adau1761 configuration and differential loopback logic . but on varying gain value in code did not got any response. kindly help

does this mean to disable mixer loopback and loopback to be done in sigma studio?
