How can I route audio from one sai to another?

[venkatesh_selva]

Hello all,

I streaming in HDMI-Input audio through sai5 and HDMI output using sai4 in iMX8MQ. How to route audio input from sai5 to sai4?

HDMI input is from Laptop HDMI output. HDMI output from imx8m to external monitor with speaker.

Using Android 8.1.0 in iMX8MQ.

Thanks

Hi venkatesh

data from one sai to another can be done with external connections

since there is no muxing capabilities, as for example in i.MX6DQ AUDMUX module.

Unfortunately SAI4 is not an external one. Checked in EVK schematic also. Is it feasible by software?

Hi venkatesh

for sai4 muxing options one can look sect.8.2 IOMUX Controller (IOMUXC)

i.MX 8M Dual/8M QuadLite/8M Quad Applications Processors Reference Manual
