I tried setting up a microphone on my laptop for recording audio and it doesn't work. It shows up on the computer in recording devices and i set it to default and checked that the levels were up and still nothing. There is no green bars when i speak into it. I tried it on another computer and it was the same so i brought it back to the shop and they got it working on their computer and said i needed an audio interface so i got one. I got the zoom u-22 and i set that up and it connected to the computer fine and the drivers were installed successfully. But still it is the same problem as when i just had the mic connected. Everything shows up fine but there is no sound. I can tell there is sound going from the mic into the audio interface because a green light flickers everytime i speak into the mic but the sound doesn't seem to go onto the computer.
