Is it just initial noise? Does this demo record noise? http://blogs.msdn.com/b/matthew_van_eerde/archive/2008/12/16/sample-wasapi-loopback-capture-record-what-you-hear.aspx

Hello,
when I'm testing the virtual-audio-capture-grabber-device with ffmpeg, I got some noise in the recorded WAV file.
Any idea where this comes from?

It's continously during the whole recording, very low though, only noticable during silence. The loopback-capture.exe does not record any noise. You can clearly see the difference when opening the WAV files with a text editor: files recorded with loopback-capture.exe just contain zeros during silence. The WAV file recorded with ffmped using the capture grabber device looks like this: ... 00 FF FF 00 00 FF FF 00 00 00 00 FF FF FF FF ...
The noise also appears in the pBuf during debugging.
Interesting...I think I vaguely recall running into it once...I'll check it out as time allows....
