I assume you’re trying to do multi-track overdubbing?

Sometimes, when you’re recording from Stereo-Mix or What-U-Hear to get internet sound, you leave those settings for live recording. Bad idea. You have to record from a specific device like Line-In or Mic-In. You will also run into delays and echoes you can’t fix without special hardware.
