I would recommend you to use the newest NCS tag for audio, as the audio development in NCS is rapidly developing.

Do you need to use NCS 2.6.0 for this? If you want to use NCS 2.6, note that you need to build and flash using the buildprog script.

Elfving when i apply and save like i set

i am using gui as i have to set several other parameters as well

Actually, i want to set preferred Audio sampling rate as 48 kHz in CIS mode. Kindly let me know what is to be added in prj. I found in BIS mode the default sampling is 48 kHz but for CIS it is 24 khz given in nrf Kconfig GUI

How are you seeing it not making a change? Are you pressing apply and save?

Using the files like prj.conf directly is an easier approach if you are not used to this GUI. That's what I typically do.

Hey Elfving

Thanks for the reply.

We are able to build the nrf5340_audio sample in BIS mod using ncs 2.6.0. When we make changes in nrf kConfig and change to CIS mode, auto save and flash then it doesnot make any change

Hello,

Unfortunately the nRF Sniffer does not see the ISO channels used in LE Audio. You would have to try other options, like for instance an ellysis sniffer.
