I finally got around to investigating: VLC not playing any sound and
displaying ten's of streams in Tools > Codec Information was simply
due to my using the wrong file extension in the output filename:

BAD!
ffmpeg -i input.mpg -c:v libx264 -c:a copy output.converted.mpg

ffmpeg -i input.mpg -c:v libx264 -c:a copy output.converted.mp4
