At least it's only on boot. My Xbox controller's headphone jack only produces garbled sounds. It also has the wobbliest headphone jack I've ever seen. No bluetooth headphone support even though the console transmits audio to the controller using bluetooth. The only other option to output audio is the HDMI-connected screen, but that disables volume controls. The volume controls that always take 10-15 keypresses to reach because it's the very last entry of the menu and the cursor can't loop around.
