Peter, thanks - I had another microSD card available so installed 
Raspbian.
Oddly, it couldn't find the HDMI audio either.

I much prefer the Ubuntu user interface and package availability, so 
will try
to be patient and wait for fixes to come along.   I can sometimes get 
omxplayer to
play a full video cleanly (though only wioth two-channel sound):

rpi3 at ewok:~$ omxplayer -o hdmi /video/video_file.mkv


Just FYI, I did an rpi-update (updated the firmware), and now even with 
the
env LD_LIBRARY_PATH workaround, the frontend segfaults:

Thanks, for your efforts, much appreciated.  Will hang in there until 
fixes available.
