When I dropped my Lucid off for service and reported this issue with no sound unless I touch any icon on the touch screen and then I get 1 second of audio, I even provided a video of this behavior. After getting the car back, the service report just said "could not replicate the problem." Well, great, nothing done. I had the same problem again yesterday and even turning off bluetooth so it could not be a CarPlay issue did not fix the problem. Only solution was to reboot... again. Becoming a frequent routine to fix an obvious software problem
