What is your setup for sound? It is not uncommon, although they have
gotten better at this, for the broadcast for a specific network or cable
channel program to have bad audio sync. TNT-HD used to so frequently
have a bad sync problem that it became a joke on avsforum, but I have
not observed it on TNT-HD in some time. If the sync occurs on one HD
channel or for one HD program, the problem is not Fios, but with the source.

All shows all channels all the time?
When I first started watching my hdtv, I noticed a lot of audio sync
problems. I no longer notice them. I'm not saying they've all gone
away. PBS had about a two-second sync problem when they first went
HD, but they fixed it.

If there had been created a universal transport stream format that interleaved
the video and audio together on a frame by frame or at least group by group
basis, along with timing tags for each such chunk, then we would not be having
such sync problems.
A local broadcaster had frequency A/V sync issues with programs fed over the
Pathfire satellite service. I looked into one of these machines and noticed
that the entire video and entire audio were fed separately. If the satellite
signal had a glitch that caused some loss of content, the timing could then
be off by however much content could not be recovered.

It's actually a feature. Every show is turned into a Bruce
Lee/Godzilla/
Mothra movie sound track.

Swell.
But the closed captioning can be even further off.
Distantly related, back in the day I used to watch network basketball
finals, but turned off the network audio and listened to the local
announcer (Chick Hearn!) call the game. Tried to do it for the
playoffs and finals here, but the *radio* is like ten seconds behind
the broadcast video. Don't know wassup with that, if the league is
responsible, or what.

Might be the tape delay radio stations use in case a naughty word comes out!

That sounds plausible for live broadcasts of excited people. Live video
feeds often now get the same treatment to protect us against a 'wardrobe
malfunction'.

Sure, but both TV and radio need the protection.
When the game moved to the west coast, tv video and radio audio were
in perfect sync, by some coincidence.
Unfortunately, the Lakers were not fully synchronized ...

s from FIOS (NOT QUANTUM) and they both have out of sync audio via HDMI (of course) and there is also an audio MUTE delay when you tune into a channel, no audio for 3 seconds
