Added support to change to javasound when DSound is not found.
This fixes problems with DSound on every plataform.

If we check if the user has DSound support before setting it, even if the user is on windows. It should fix this.

Anyway this is a very uncommon issue. Especially under windows XP.

ok for 2.5.1. I can reproduce it always in the same computer so I can debug it. Let me know if you already know what to see.

Hi Francisco,
This appears to be a corner case for now. I've never seen an issue like this one before. However, let's push it out to 2.5.1 for a better look.
