New Post: Error :- MemoryAllocationError calling waveOutOpen while playing in a loop

you should be doing your waveOutStream Init and Play outside the loop, and use a BufferedWaveProvider to feed wave out. Inside the loop, you shuold put the data received into the BufferedWaveProvider.

Also, from your code, it looks like you are on a background thread so I recommend using WaveOutEvent instead of WaveOut for playback.
