I had this same problem with ATSC recordings of Fox shows, only Fox.
Usually the audio started out OK and then went into devil-talk partway
in. Sometimes normal audio would return, usually not.

I transcode all my recordings with ffmpeg and was just keeping the
broadcasted AC3 audio stream intact, so I changed the codec to MP3
(libmp3lame, actually) and so far the problem has not returned. Maybe
ffmpeg is "fixing" the sampling rate during transcoding?
