It's a quite well-known fact that some newer sound cards are not capable of providing direct playback from a microphone to speakers, and even the ubiquitous Realtek HD sound card models have this problem. Though at first it may not sound much, this is actually an important feature for those who have to work with karaoke apps, DAWs and audio mixing tools and cannot hear the stream from a microphone through speakers. Anyway, to solve this problem one doesn't have to replace the sound card or even buy expensive extra mixers. A more convenient solution is at hand, and its name is Microphone Pass-through (Playback) Emulator.
Microphone Pass-through (Playback) Emulator is a small and handy tool created specifically to deal with the aforementioned issue. This tiny utility will emulate the pass-through playback; in other words it will pass the input from a microphone through speakers and directly to the background. It's very simple and easy to use as it comes with a neat and intuitive interface. The interface lets you select the input and output devices, the priority level of the thread, as well as a sampling rate and format, thus enabling you to control the output volume.
To sum it all up, Microphone Pass-through (Playback) Emulator is a nice tool that offers an undeniably handy method of solving the problem of not working direct playback from a microphone to speakers, a problem that quite many sound cards come with.
