Hello, I'm using two NRF5340 Audio DKs — one as a Gateway and one as a Headset — running the nrf5340_audio example. Is it possible to configure the Headset device to output audio via USB while maintaining audio input through I2S (LINE IN) on the Gateway? How can I integrate an external electret microphone on the Gateway to replace the built-in PDM MEMS microphone? Currently, I'm using LINE IN on the Gateway with an external microphone, but the audio is sent to the Headset as audio data. When output through the Headset, it is recognized as audio data rather than microphone data. I'm currently using an external DAC on the Headset device in this set up but I would like to use the NRF5340 to do this task instead. Thanks!

NRF5340 AUDIO DK, USB audio output Headset device & Microphone input on Gateway

Hello,

I'm using two NRF5340 Audio DKs — one as a Gateway and one as a Headset — running the nrf5340_audio example.

Is it possible to configure the Headset device to output audio via USB while maintaining audio input through I2S (LINE IN) on the Gateway?
How can I integrate an external electret microphone on the Gateway to replace the built-in PDM MEMS microphone?

Currently, I'm using LINE IN on the Gateway with an external microphone, but the audio is sent to the Headset as audio data. When output through the Headset, it is recognized as audio data rather than microphone data. I'm currently using an external DAC on the Headset device in this set up but I would like to use the NRF5340 to do this task instead.

Thanks!
