I am not familiar with the HUD system, but based on your description of multiple symptoms, one can speculate that you have a problem higher up on the "ladder" - it still could be a fuse that you did not find, or a single module responsible for those malfunctioning items... I can't imagine a single module responsible for HUD and sound from the radio, so it would fall back into fuse, wiring, or water/moisture damage in the electronics location.
Have you checked the fuses visually or using a meter? how many locations for fuses do you have and have you checked all of them? How did the problem start in the first place? was it after a heavy rain? a day on a track? a spilled drink in the cupholder? service visit to your friendly local dealer? or repair shop?..
