@Jörgen Regarding your specific question about the speed warning, I do not share your opinion. However, I do agree in general that all sounds in MRA, whether it's a beep for a speed warning or a voice instruction, are not easily adjustable. This is especially true when you have other apps running in the background (radio, Spotify, Flitsmeister, etc.). I would prefer to have the ability to control the volume of these sounds within the app. The options currently provided in the Audio menu are insufficient for this purpose.
