A common problem with fifos, as they don't do any buffering...  The
sending and receiving app aren't in-sync regarding how much video/audio
they input/output.

You can either make one (eg: audio) a real file, or you can run
two separate instances of mplayer...  One outputting audio to a fifo, no
video, and the second outputting video to a fifo, no audio.

Don't trust me! I'm wrong!
