VB.NET - MPEG-4 Screen recorder. May 23rd, 2015 update

[Peter Porter]

vinodvin42, the polished looking version you quoted wont be available online as a project file. It has some extras, but it uses the same recording code as my older version.

Have you downloaded the FFmpeg static build and placed it within this project's resources folder? It needs FFmpeg in order to record audio as well as video.

The recorder was designed to work with older versions of FFmpeg below, but might work with the latest static builds now.
32bit version
64bit version

If you have FFmpeg, the only other thing could be is that you don't have your system's Stereo Mix enabled.

Enabling Stereo Mix for Windows Vista, 7 and 8
* Right-click over the Speaker icon by the system clock then choose Recording Devices to open the Recording tab of "Sound".
* Right-click Stereo Mix, and from it's dropdown menu, click Enable.

Note (Vista, 7 and 8):
If you don't see Stereo Mix, right click within the Recording tab window, then check "Show Disabled Devices".

Enabling Stereo Mix for Windows XP
* Click the Speaker icon by the system clock.
* In the window that appears, choose Options then Properties.
* In the next window, click the "Recording" radio button, then in "Show the following volume controls", click in the box for Stereo Mix, then "OK".

Sorry, I've been busy with other things. I'll try to post an update soon for the downloadable version.
