Hi,

We have checked from our side, and cannot reproduce the issue.

Could you try the following steps?

0. make sure we have stash/backup all the changes, or finish the commit

in NCS, I add the git remote
$ git remote add dual_mic https://github.com/rick1082/sdk-nrf.git
fetch the example
$ git fetch dual_mic dual_mic_sample_2_4_2
checkout the branch
$ git checkout dual_mic_sample_2_4_2
run west update
$ west update
go to nrf/applications/nrf5340_audio/tools/buildprog and use buildprog.py to build the program and flash

I changed to v2.4.2 and built it, but the same error occurs.

error: Aborting due to Kconfig warnings

I looked at the relevant line in kconfig.cmake (attached file), but I don't know why the return value of execute_process is 1.

That sample is for v2.4.2. Could you build it with NCS v2.4.2?

I'm sorry it's taken some time to reply.

This is exactly what the above demo code would like to achieve.

Hi,

Rather than implementing two microphones in one receiver, I would like the gateway to output microphone signals from two headset boards at the same time, as shown in the figure below.

Is it possible to achieve this with code editing for nrf5340_audio?

Regards,

Gotoda

Hi,

Seems you want two microphones to one receiver. If so, there is an unofficial https://github.com/rick1082/sdk-nrf/commits/dual_mic_sample/ for v2.4.2. You also could ping our FAE in JP to see the demo.

“Beware that this code/configuration is not fully tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.”
