I ran into a similar problem, although I was using a RandomAccessFile, instead of a BufferedInputStream, to read the PCM data. The issue was that the file I/O was too slow. I suspect you will have this problem even with a buffered stream, because the I/O is still taking place on the same thread as audio processing.

The solution is to have two threads: A thread that reads buffers from a file and queues them into memory, and another thread that reads from this queue and writes to the audio hardware. I used a ConcurrentLinkedQueue to accomplish this.

I used the same technique for recording, using AudioRecord, but in the reverse direction. The key is to place the file I/O on a separate thread.

I just saw the logcat: obtainBuffer() track 0x298b18 disabled, restarting .. that is to say : you have not got audio data and the input audio stream have been stopped .so the buffer must wait for the audio stream in. i think you should check the inputstream and the read method. you must ensure that you have read the audio data continuously.
