Have you ensured that headphone simulation is selected as No and that for cabin announcements the PA button is pulled up and volume dial turned up? No issue here in Xbox x with sounds on A350.
Chap GPT says this is expected behaviour at certain airports where there might be a discontinuity in the flight plan or a manual leg or ACT vectoring after take off. I followed the Chat GPT steps to resolve (eg, Edinburgh airport), but it doesn’t work - plane still does not follow flight plan in the FMS.
Same problem here - despite the NAV annunciation after take off, the a350 does not follow the flight plan. Direct to has to be enabled to a waypoint to enable the following of the plan.
Perhaps coincidence, but since the update two days ago to 1.2.0 on Xbox the OIS no longer computes takeoff performance to be sent to FMS. Anyone else experiencing this?
