Narrative:

Atx X taxiing toward the active runway, while performing checklist, lax tower cleared us to position and hold on runway 24R. I taxied the aircraft into position and hold on runway 24L, frequency very busy and I couldn't confirm assigned runway (we made attempt to confirm runway assignment). At this point, traffic was cleared to land on runway 24L. ATC advised the landing traffic to go around and for us to exit the runway. No incident occurred.
