i.MX6 Audio port (AUDMUX port ) as Input and Output simultaneously

[ndsonu]

Hi All,

We have our audio connection around the i.MX6 as below.

Here, we are trying to use audio port 6 as a transmitter (master)  and receiver (slave)  simultaneously.

AUD6_RX - needs to be a slave and receives I2S audio from INAP375R chip.

AUD6_TX - needs to be an I2S master and will push I2S data to an audio codec ( SGTL5000).

Please note that we have connected two different devices to TX and RX lines of same audio port.

Is this configuration supported/allowed  from both HW and SW (Linux) perspective?

Thank you for your support!

Thanks,

Sonu

Hi Sonu

yes AUDMUX module supports this hardware configuration.

In software you should write own custom driver for it.

Best regards
