Recently my IDT High Definition Audio CODEC was deleted but I reinstalled it and the laptop recognizes that it has speakers and it says they are working; however, when I go to PlayBack Devices ->Speakers and Headphones -> test it says "Failed to Play Audio Tone". When I plug in my headphones and check the test tone plays but then when I go on Youtube or Khan Academy no audio from the videos is played. Also with my speakers absolutely no audio is played, as in I have not heard any audio from the speakers at all! How should I fix this?
Thanks so much!
