Check the schematics as this can't be right. SD_DAT2 is connected to the eMMC controller on CM5 Lite modules. It has no other function and isn't connected at all on non-Lite modules.But I also have an audio card using i2s which has I2SLRCk on the SD_DAT2 pin 69.
I2S WS is only available on GPIO19 aka pin 26 according to the CM5 datasheet.
