nRF5340 Audio-DK [HEADSET][UNICAST_SERVER] - Failed to establish the LE Audio connection to nRF5340 Audio DK from Samsung Galaxy S24+.

Hi Team,

I have 1 nRF5340 Audio DK. With the steps mentioned in below links, I configured Json file to Headset and I'm able to achieve it.

Setup Details :

Gateway - Samsung Galaxy s24+.
SDK Version : nRF Connect SDK v2.6.1
Application: nrf5340_audio.

Procedure:
Step 1: Build SDK with nrf5340_audio with below mentioned configurations.
Step 2: Flashed board with application and then performed reset.
Step 3: Connetion is initiated from Bluetooth settings page to DK.

Observations:
When trying to enable LE Audio, it is failing. No LE Audio connection is established. However GATT level connection has established.

HL [00:00:29.543,273] <inf> bt_content_ctrl_media: Discovery of MCS finished

No communication is observed after above service discovery procedure.

In prj.conf, added following configurations. (These configuration are referred from previously answered questions)
