I can confirm, that the file is not handled porperly and sounds
distorted. Will fix it.<br>

Actually the file is broken. These are the header parameters:<br>
blockalign = 1<br>
width = 8<br>
depth = 16<br>
av_bps = 22050<br>
frequency = 22050<br>
channels = 1<br>
bytes_per_sample = 1<br>
bps = 22050<br>
caps = audio/x-raw, format=(string)U8, layout=(string)interleaved,
channels=(int)1, rate=(int)22050<br>
</blockquote>
<br></div>
Oh, and also the avg_bps is wrong. Needs to be 44100 for 16bit.<font color="#888888"><br>

From various places you can check the wav format spec:<br>
<a class="m_3502431828139060249moz-txt-link-freetext" href="http://soundfile.sapp.org/doc/WaveFormat/" target="_blank">http://soundfile.sapp.org/doc/<wbr>WaveFormat/</a><br>
BlockAlign == NumChannels * BitsPerSample/8<br>
The number of bytes for one sample
including<br>
all channels.<br>
<br>
The issue is that blockalign=1, but for 16bit, it must be >= 2.
We can probably add a workaround, not sure what others think. If
you can please also report to the software that created the file.<br>

Are you sure the 16bit wav file is well formed?
According to the output gstreamer plays it as 8bit,
which explains the noise. Can you share this file?<br>
