naudio - C# Audio File is played in a loop although it is stopped -

i have older implementation using naudio 1.6 play ring tone signalling incoming call in application. user acceptes call, stop playback.

basically follwing done:
1. event call must signalled, timer started
2. inside timer play() on player
3. when timer starts again, check performed if file played checking currenttime property against totaltime propery of wavestream
4. when user accepts call, stop() called on player , stop timer

the point is, run in cases playback still repeated although timer stopped , stop() called on player.

in following link read classes bufferedwaveprovider , wavechannel32 used in code padding buffer zero.

is possible non-stopping playback due usage of classes bufferedwaveprovider , wavechannel32?

in naudio 1.7 audiofilereader class there. class padding zeros? did not find property padwithzeroes in class. make use audiofilereader in case of looped playback?

below code of current implementation of timerelapsed

    void timerelapsed(object sender, elapsedeventargs e)     {             try             {                 wavestream stream = _audiostream wavestream;                 if (stream != null && stream.currenttime >= stream.totaltime   )                 {                     startplayback();                 }             }             catch (exception ex)             {                  //do actions here             }         } 

the following code creates input stream:

    private wavestream createwavinputstream(string path)         {             wavestream readerstream = new wavefilereader(path);             if (readerstream.waveformat.encoding != waveformatencoding.pcm)             {                 readerstream = waveformatconversionstream.createpcmstream(readerstream);                 readerstream = new blockalignreductionstream(readerstream);             }              if (readerstream.waveformat.bitspersample != 16)             {                 var format = new  waveformat(readerstream.waveformat.samplerate, 16,  readerstream.waveformat.channels);                 readerstream = new waveformatconversionstream(format, readerstream);             }              wavechannel32 inputstream = new wavechannel32(readerstream);             return inputstream;         }
