After trying to record something in WavePad using the line-in port on the back of my computer, I can no longer hear any sound on my computer using speakers or headphones. The recording I tried to do worked a day earlier, but the day after that, it wasn't able to record and now my whole computer can't play anything back. This happened right after I tried and failed to record something.
I've already tried updating/uninstalling the audio drivers, but that didn't work. Any help would be greatly appreciated.
