Open AL, Adobe Director - No sound in projector [FIX]

One of the most annoying thing about Adobe Director is its lack of support. Open AL Xtra enables director to use OpenAL runtimes for 3D sound manipulation. Unfortunately, in a projector/exe, it doesn't play any sound. This issue was pointed out at multiple forums (here and here), without any fix so far. After struggling for nearly 4-5 hrs, I finally figured it out. The solution couldn't be any simpler. Just include these two xtras in the projector.

- Mix Services

- Sound Import Export

I got he hint from playFile() documentation for Director. It mentions the use of "Correct Mix Xtra" to play sound properly.

Recenberg 1/5th success rule applied to life..

For those who are not familiar, Rechenberg's 1/5 rule refers to adaptive mutation in evolutionary strategies (ES). It says that the ratio of successful mutations to all mutation should be 1/5. Deriving from this idea, if you get too successful (i.e., more than 1 out of 5 tries) then you're converging too fast to a local optima (aka safe options) and will result in stagnation later on. So, don't run after too many successes. Ideally, at-least according to Rechenberg, one should try 1 safe thing for every 4 risky things in life to optimally balance stagnation vs. growth.
