android - AudioTrack buffer underrun when streaming from bluetooth socket -

i testing concept of android application allows stream bluetooth on rfcomm (from pc phone). able transfer audio computer phone no problem , start streaming audio. problem audio begins stutter , buffer underrun error message audiotrack. reading socket taking time. when timed it, underruns occurred when takes >= 1000 milliseconds read return, when on average takes few hundred return. here code below:

    public connectedthread(bluetoothsocket socket) {         this.setpriority(max_priority);         mmsocket = socket;         inputstream tmpin = null;         outputstream tmpout = null;         // input , output streams; using temp objects because         // member streams final.         try {             tmpin = socket.getinputstream();         } catch (ioexception e) {             log.e(tag, "error occurred when creating input stream", e);         }         try {             tmpout = socket.getoutputstream();         } catch (ioexception e) {             log.e(tag, "error occurred when creating output stream", e);         }         minbuffsize = audiotrack.getminbuffersize(48000,  channel_out_mono,  audioformat.encoding_pcm_16bit);         m_audiotrack = new audiotrack(audiomanager.stream_music, 48000, channel_out_stereo,                 audioformat.encoding_pcm_16bit, minbuffsize /* 1 second buffer */,                 audiotrack.mode_stream);          mmbuffer = new byte[minbuffsize * 2];         mminstream = tmpin;         mmoutstream = tmpout; //        distream = new datainputstream(new bufferedinputstream(mminstream, 1000000));         distream = new datainputstream(mminstream);     }      public void run() {          int numbytes = 0; // bytes returned read()          // keep listening inputstream until exception occurs.          boolean firstrun = true;          while (true) {              try {                 final long starttime = system.currenttimemillis();                 distream.readfully(mmbuffer);                 final long endtime = system.currenttimemillis();                 int temp = m_audiotrack.write(mmbuffer, 0, mmbuffer.length);                 system.out.println("total execution time: " + (endtime - starttime) );                 if (firstrun) {                     m_audiotrack.play();                     firstrun = false;                 }             } catch (ioexception e) {                 log.d(tag, "input stream disconnected", e);                 break;             }          } 

any suggestions on how can speed reads socket or prevent underruns in general?
