Hi Nordic team,
I'm trying to stream audio from the nRF5340 DK to a BLE headset (Sony inzone buds) using the [Unicast Audio Client sample] with the BAP profile.
Initially the device was not scanning properly, got err:-5 when starting scan — resolved by adjusting configurations based on this forum thread:
added the hci_ipc.conf file.
https://devzone.nordicsemi.com/f/nordic-q-a/116647/failed-to-use-periodic-advertisement-function-on-nrf5340dk
After resolving scanning, I encountered:
Unable to find sink PAC
during discovery. See logs below with debug logs enabled.

I could able to connect via nrf connect and view multiple uuid's related to LE Audio, refer below long screenshot.
Kindly guide me through this.
Thanks.
