Try enabling/disabling opengl vsync.
On the CW 54 in Baltimore the audio gets very out of sync without
opengl vsync enabled, but it causes other problems on other channels.
I guess it has something to do with how they're encoding their video.
Other stations in other areas could be doing similar things that could
be causing your problem.
