Session, only interesting thing in it (compared to the session it was derived from), is that I committed offline a couple of aux busses.

Anyway, some tracks are now silent – there's audio in the timeline but nothing metering. No inserts. If I insert a trim DSP plugin, no change; if I convert to Native, audio returns.

Restarting Pro Tools fixed it, so just noting for posterity.

I'm on 2018.7 Ultimate on HDX, macOS 10.12.6, MacPro5,1.
