I've bought the garmin 955 solar for 4 months,and find there's no beep sound in any notification or activities recently,is it a software problem or hardware problem?
I am pretty sure I found the answer to this as I also had the same issue. If you go to settings and all the way down to system - sound and vibration - notification during activity (or something along these lines, I am translating from norwegian) , make sure to activate this setting and see if it helps?
