Summary	07884: travrusa: Sound plays randomly when you jump rivers using the broken bridge
Description	When you jump across rivers using the small broken bridge, the jumping sound plays randomly instead of playing all the time. It seems to be a regression introduced after the major sound system rewrite a couple of versions before.
Steps To Reproduce	Play the game and try to use the broken bridge to jump across rivers. Sometimes it will play the jumping sound and sometimes it won't play any sound.

So, you must try to jump on at least 3 or 4 of them at full throttle to see that most of them won't reproduce the jump sound effect.

This happens in 4:02, he jumps-cross the bridge and the sound is present. In 4:24 there's another jump and the sound doesn't trigger, so MAME emulation is loyal to the original machine and we can close this report as BTANB
