Recently my mic stopped working on my desktop, so I tried it on my laptop and it worked fine. I'm guessing now it's my sound card. I cant seem to be able to figure out how to switch to my integrated sound, though. Any ideas? Thanks in advance!

It would help if you were to list the make and model of your computer, and if it is a custom build list the motherboard.

Some motherboards will automatically switch from the onboard audio to the PCI card and back. Some you will need to go into the BIOS to enable either function.
