Netflix has low or no audio when I watch on my Mac or PC.

Low or no audio when trying to stream can be caused by a problem with some of the temporary files stored on your computer, which are used by the Silverlight player to play your movie or TV show. These types of audio issues can also be caused by one or more audio settings on your computer. To attempt to fix this issue, try the steps below for your Mac or PC.
