a.What is the make and model number of your sound card?
b.Do you mean to say that you want to project your microphone output to your laptop speaker?
If question b is true, what you’re trying to achieve here is called microphone pass-through that directs playback from microphone to speaker. However this feature is not supported by all sound cards.
1.Find out from your sound card manufacturer if this feature is supported. If so, you will need appropriate driver that supports the feature. Visit the support section of your sound card manufacturer’s website
to get the driver.
2.Install third party software that has the capability to enable this feature.
