I have a PCM3070EVM-K eval board connected to a DEM- DIR9001 eval board via CN005 of the DEM board and J14 of the TAS1020 USB controller. I have a PPS topology that switches, with a mono mux (2 to 1) between an analog input and the DIR9001 I2S output. The audio switches correctly between the analog input and the I2S input but when I disconnect the S/PDIF input to the DIR9001, the audio then becomes garbage. To restore the correct operation, I need to Build "disconnect" with the PPS and Build "download code" again (to get to blue screen). What am I missing?
