I play a test file, that's it.
as mentioned shortly, oss emulation may call prepare multiple times. since the oss driver changes the configuration by calling ioctls many times, e.g. one for sample rate, one for sample format, etc., at each time these ioctls are called, prepare callback is called, too, to reflect the change of configuration.
