Another piece of information. Looking at the documentation for ffmpeg, it mentioned ffplay. So I tried that in Terminal (attached) and the sound was working. So what's so different between ffmpeg a& ffplay? BTW I reverted back to the get_iplayer ppa for ffmpeg as that ppa (using ffmpeg) works Ok on my other barebones PC and laptop.
