EDIT: Sorry! I answered without first reading the article. What I'm talking about below is different from TFA.

You could record the audio to an audio cassette tape. If you had a good enough cassette deck, you could use acoustic coupling (holding up the tape deck to the TV speaker).

The BBC Micro had a 7-pin DIN socket for audio in/out and remote control of an external tape deck.

Thanks for that! That makes sense and is very cool. In the US in the 80s we did something similar from the radio (the UK probably did too). So, I assume it was a similar principle.

Love it.
