Comment:

 Replying to [comment:5 Lawrence Rust <lvr@…>]:
 > No, not tried AC3.  All my recordings are either mpeg2/mp3 with some mp4
 if transcoded.  The audio output device is to ALSA analog.

 That was a good clue.  When setting the output to be stereo (via Audio
 Settings), 2-channel AC3 recordings produce plausible visualizations, at
 least when using the Spectrum visualizer.  There are still some oddities
 to sort through -- it often appears that only the left half of the
 spectrum is active (could this be two-channel mono?), and some recordings
 show very low levels on the Spectrum visualizer relative to the volume on
 the TV.

 That said, I also noticed that when you enable the Spectrum visualizer and
 enter the cutlist editor, the visualizer conveniently continues to be
 displayed.  This means that the patch's functionality is already more or
 less present, though not in themeable form.
