Volker Ruppert ee6bfaa4c4 Added separate thread for the PCM data conversion. Only in case of dual output
sendwavepacket() directly calls the conversion method and output(). In all other
cases it puts the unmodified data into a buffer and the conversion thread is
doing the main job and puts the data into the output buffer chain.
TODO: resampling could also be done by the new thread.
