For about two weeks now the audio will go out on only the FoxNews Channel. We’ve reset our box several times and it will start working for a while until it doesn’t. It’s strange that only one channel is being affected.
Reminds me of this post. I would call in to report it or email Cox at firstname.lastname@example.org. I think it's something on the back end of Cox. The only thing I would check on your end is to try enabling then disabling SAP. See here for instructions.
