Sounds Not Working

For Some Reason Some Sounds Won't Play
These Sounds Are:
Start
Countdown (Sometimes)
Trick
Boing
Track Music (If It Is From YouTube)
Race Finish
Item Roulette
Item Deploy
Item Drop
Spin Out
Bonk
2nd Lap
Results
And Sometimes Item Box Shatter.
Why Won't These Sounds Play?
Is It A Mobile Thing?
