Flash Player 10.1: New Timing Model

Hi,
A couple of people approached me lately with issues due to using Flash Player 10.1.

The main problems that are presented by these people are basically out-of-sync sounds in their applications.

For example, one client approached me with a game similar to Simple Simon:

In his game, the interval between the played sounds sometimes changes, causing the timing of the melody to go way off.

Did anyone encounter this kind of issues caused by Flash Player 10.1 due to its new timing model?

What are possible solutions to this problem?

Thanks
