Function pev_cm_mnbc_sound setting wrong value for CNT field

[vinicius-smartme]

The function pev_cm_mnbc_sound is setting the wrong indicate->MSVarField.CNT due post-decrement operator inside the while condition, what is causing the CNT field to be one below the expected value.

As a suggestion, just replace the while(sound--){} for do{ ...}while(sound--);
