+   This class wraps the platform specific /dev/dsp implementation.
+   The only unusal thing is, that it supports each order of
+   init/open.
+   i) you can first init the device and the open
+   ii) you can first open the device and the init it
+   The implementation takes care that the calls are forwarded
+   in the right order to the /dev/dsp implementation.
+   (means: before the init it, we need to open it)
+   But a caller can do it in both orders.
