Do all the things mentioned above to see if you can get it to work.....

Understand this: A USB mic is essentially a one way sound card. Sound goes in but not the other way around. Most computers have a hard time dealing with 2 sound cards at the same time. They like to work with one thing at a time.

When you plug in the mic, it apparently is becoming the sound card the computer uses.... and since it has no output... you hear nothing.

You would need to select the factory card (internal) as the output. The problem with this is that the clocks in the 2 cards don't sync and if you can get it to work at all, you will very likely have audio sync issues on playback.

The solution is a professional quality USB sound card/interface which allows you to use a real mic (as opposed to a USB mic) and which handles the input as well as output of the music all in one package that is running ASIO drivers. USB mics have their place and purpose but it is NOT in recording and playback of multitrack music in the manner we do things. It is possible to use a USB mic, but it is generally not the most optimal or convenient way to do recording.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
