Actually, you have just described an issue I'm now having with 0.20
which I haven't seen before - older recordings (DVB-T in the UK) made
with <= 0.19-fixes sometimes play with the silent soundtrack - the
only fix I can find is to use the next/prev soundtrack options to
switch to the correct one.

Live TV always appears fine, so I presume there is some sort of
detection going on when playing recorded material which is now getting
it wrong sometimes.

Any ideas where this might be, or what appropriate logging level I can
switch to to see what's going on?
