Comment 3 for bug 1551581

This is the dynamic brake sound trigger in the sms:

               Discrete_Trigger ( 45
                  SetStreamVolume ( 1.0 )
               )
               Variable_Trigger (
                  Speed_inc_past 4.0 Startloop ( 1
                     File ( "30-fel2.wav" -1 )
                     SelectionMethod ( SequentialSelection )
                  )
               )
               Variable_Trigger (
                  Speed_dec_past 4.0 ReleaseLoopReleaseWithJump ()
               )
               Discrete_Trigger ( 46
                  SetStreamVolume ( 0.0 )

Which is an over complicated setup, that tell to the game, that the dynamic brake sound should be stopped below 4.0 m/s (14 km/h).

There is a self explanatory easier setup to replace that, that works without problems:

               Variable_Trigger (
                  Variable3_inc_past 0.05 Startloop ( 1
                     File ( "30-fel2.wav" -1 )
                     SelectionMethod ( SequentialSelection )
                  )
               )
               Variable_Trigger (
                  Variable3_dec_past 0.05 ReleaseLoopRelease ()
               )
