Hello all,
I am trying to run bap_unicast_server example with nrf5340_dk. I used no sysbuild configuration. Then I manually added hci_ipc as it shown at ss 
I flashed succesfully by using --recover command.
However, I got ISO server error.
bt_ascs: Failed to register ISO server -134<ESC>[0m<CR><LF> Location successfully set<CR><LF> Supported contexts successfully set<CR><LF> Available contexts successfully set<CR><LF> Advertising successfully started<CR><LF>
I increased stack size to CONFIG_MAIN_STACK_SIZE=4096.
