Dear coukou,
I recently read all of our posts again and then discovered the source of the sound you showed in post # 2726.
And as I wrote above, this sound is on Arimi's ux speedcam.zip.
So at that time (2020.07.01) you were using Arimi's ux but only now have I discovered this.
In this new screen you show that you have the correct ux.
There are two things I've tried to explain to you:
- if you drive below the allowed speed the sound will not play;
- the "Sound approach ..." alert I never used and at the moment I can't do any tests because I haven't left the house for four months because of the virus.
