I noticed the values after decode is very much different from the values of the original PCM samples. For cases when the PCM sample values are constant (because no one is speaking), the decoded values fluctuate too. These fluatuations are causing the background noise. Is my observation expected?

could be a million different things, unfortunately. Focus on comparing
your code to the Speex examples, and looking for places where they
diverge. Also, try taking Speex out of the picture altogether, just to
make sure you can send plain uncompressed PCM audio through your network

[Speex-dev] Integrating speex with VideoNet application: Constantbackground
changed the m_waveFormatEx.wBitsPerSample for both record buffer and playSound
buffer, changed my array from char to short and I'm still getting the same
constant background noise. I notice that when I talk into the mike, I will get
a slightly louder noise, can't hear any clear speech... Any idea what's
