Thanks, Chris.  Here is some more logging that occurs when I click the
"softer" and then the "louder" button at each end of the volume slider
for this player on the LMS web page.  The error message I sent
previously seems to have come from the "softer" command, which sends
"new SB vol: -2".  As you can see below, there is a different error
associated with the "louder" command, which sends "new SB vol: +2".  It
doesn't look like either of these actions actually sends a signal to the
receiver (i.e., there is no change in the receiver's display when the
buttons are clicked), but the volume of the player goes up and down as
the buttons are pushed, presumably through the internal volume control
for the player.  Clicking on the volume slider between the "softer" and
"louder" buttons sends a signal to the receiver (i.e., the actual volume
briefly appears in the receiver display, and the volume of the player
jumps to the relevant setting) and the volume goes up or down as
expected.

I have changed the audio setting for this player so that the output is
fixed at 100%, and I get the expected result.  No change in volume when
either "softer" or "louder" button is clicked on the web page, but the
volume jumps up and down when the volume slider is clicked.  I would be
happy changing the volume that way from a browser, but unfortunately,
the Sqeeze Ctrl app for Android doesn't let you change the volume when
the audio setting for the player is fixed at 100%.  (This may work
differently in iPeng, since my wife could change the volume from her
iPad in iPeng, even when the volume of the player is fixed at 100%, and
I don't see errors in the logs when iPeng changes the volume.)  Any
suggestions?
