Well, you're right, I don't know what I was thinking. That's what happens when you compare emulators with 3 beers in your body.

I noticed too the sound engine (and the croud) disappearing but i use mame 0.227 and the behaviour is the same. Are you sure that mame 0.220 has sound ok?
UPDATE: It turns out Stadium Cross is one of those games that has a separate sound route for the engine speakers (requiring its own machine config). That will require a bit of research.

The truth is that it is quite strange, the sound of the engine of my bike did not sound when I was alone on the track (I let my rivals overtake each other) except in the jumps, that is, only the voice of the commentator was heard during the whole race. In version 0.220, when doing the same exercise above, the sound of my engine is heard constantly.
The strange thing is that now, when reloading the game again in FBN, you hear the engine of my bike constantly during the race.
I really have no idea how it happened.

I think I know what happens. When I start the game with Multi-Screen Mode on, the sound of my bike goes away during the race, but when I start the game to display it on one screen (Multi-Screen Mode off), the sound of my bike's engine is constant throughout the race.

I noticed another thing, not always the sound of the engine of your bike will sound during the whole race when you first load the game, but curiously, when you restart the game (F3), the sound of the bike comes back during the whole race...
The truth is like random, and when the sound of the engine of your bike does not sound when you just load the game, you just have to restart (F3). I tried this 5 times and it worked.
This "tip" works in both:
Multi-Screen Mode: Enabled
Multi-Screen Mode: Disabled
