- soundlow: use direct output if no PCM callback is registered. - soundlow/soundfile: re-implemented openwaveoutput() method to support runtime changes of wave mode or file (only implemented in the 'file' driver, stub for others). - soundfile: don't initialize mixer thread and PCM callback if thread is already running / no output() delay in that case.
