I concur. Seems to be only live TV. None of my recordings so far, have
been missing audio. However, trying your example, if I tune to channel
9, select track 1, then tune to 7, I get no audio. In fact, whilst on
7, I can switch between track 2 (audio) and track 1 (no audio).
Also note, the suggestions around earlier, about changing to TS instead
of PS, seemed to make no difference.
