Okay, so I somehow set up my Windows 7 laptop to play iTunes through the laptop speakers during a video call, while the video call sounds as well as almost all others come through my headphones. This was a long time ago, and I do not know how to turn it back. In an attempt to fix this, I opened playback devices, and disabled my laptop speakers. This did not solve the problem, but rather made it so iTunes will not even play anything. I hit play on a song, and the play triangle symbol turns into the double barred pause symbol, so I know that iTunes is not frozen. I tried restarting my computer and iTunes as well, neither attempts have solved this problem. Is there a way I can return to default settings on all my sound and playback devices? Any help is much appreciated.
