Disable all other McASP nodes. Audio input is currently not working properly, so the RX port on McASP1 is disabled for now, until the issue is debugged. The serializer is shared between HDMI and codec. By default codec is used for output, but it can be toggled to HDMI using a FET switch connected to the MCASP1_FET_SEL (J24) header on the board.
