Dear sir.

I use wave to play a .wav file. I found the wave is deadloop. the information is:
# wave start.wav 
SampleRate = 44100, Channels = 2, SampleBits = 16
Format Signed 16-bit Little Endian 
Frag Size 3760 
Total Frags 64 
Rate 44100 
Voices 2 
Mixer Pcm Group [Wave playback channel]

When I trace the code I found the program will deadloop in while (N < mSamples && n > 0)
I don't know why.  the mSamples = 1361076, After N > 240000 the program deadloop, but key still can use.

By the way, I can not get any data from DMA. I check the I2S, it does not send any data.
