Description
Is your enhancement proposal related to a problem? Please describe.
BAP defines sets 441_1_1 and 441_2_1

and audio configurations (AC) 11(i) and 11(ii)

But using these configurations in the LE Audio BSIM tests (as seen by #75816) fails due to rejecting due to not being able to schedule with the expected latency.
The rejection happens in
if (!cig->central.test) {
/* Make sure specified Max_Transport_Latency is not exceeded */
if ((c_latency > cig->c_latency) || (p_latency > cig->p_latency)) {
/* Check if we can reduce RTN to meet requested latency */
if (!cis->central.c_rtn && !cis->central.p_rtn) {
/* Actual latency exceeds the Max. Transport Latency */
err = BT_HCI_ERR_INVALID_PARAM;
/* Release allocated resources and exit */
goto ll_cig_parameters_commit_cleanup;
}in ll_cig_parameters_commit (https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/bluetooth/controller/ll_sw/ull_central_iso.c#L522-L532)
Describe the solution you'd like
The controller should support this audio configuration with these parameters.
