The static method which builds the sound driver instance In case of failure, can throw one of these <a class="el" href="a03814.html">ESoundDriver</a> exception objects: <a class="el" href="a03819.html">ESoundDriverNotFound</a>, <a class="el" href="a03816.html">ESoundDriverCorrupted</a>, <a class="el" href="a03821.html">ESoundDriverOldVersion</a>, <a class="el" href="a03822.html">ESoundDriverUnknownVersion</a><p>
You can request support for EAX. If EAX is requested and if there is enougth hardware buffer replay, then only hardware buffer are created when calling createBuffer. If the number of available hardware buffer is less than 10, then EAX is ignored.
