Replying to myself...

Enabling 'extra audio buffering' fixed the problem for live tv. I
thought I had previously tried that setting but I got it confused with
the "agressive sound card buffering" one that lives in a different menu.
  I'm still not sure why it needs this option on for live tv but not for
prerecorded shows (even if they are still being recorded as I watch them).
