There's no magic, data is data.

To help debug your code I would write the network stream to disk along with
an appropriate wav header and see what it sounds like played back.

It the sound output is random noise then it would seem the data isn't
getting copied into the sound buffer. Sometimes for debugging sake it's
worth replacing the copy with a data set that initializes the buffer to a
series of bytes that represent a tone. A crude square wave will do such as
{5000, 5000, 5000, 5000, 5000, -5000, -5000, -5000, -5000, -5000}

I don't know anything about .NET that would be special here. What
interface are you using for sound output?
