<Sound Dev> JDK 9 RFR of JDK-8039863: Fix fallthrough lint warnings in sound

[Joe Darcy]

Hello,

Please review a fix for

     JDK-8039863: Fix fallthrough lint warnings in sound
     http://cr.openjdk.java.net/~darcy/8039863.0/

Without having domain knowledge of this code, it wasn't clear to me 
whether or not the fall through was intended.

Thanks,

-Joe
