I ran the vlc & ffplay commands suggested above to give a log which is attached. Is "mpgatofixed32 audio converter error: libmad error: bad main_data_begin pointer" in the vlc significant as it's not in the ffplay log? ffmpeg version 3.2.6-1~backport1.1~xenial package is part of the get-iplayer ppa, which as I said before causes no problems in my other 2 Xenial PCs..
