Campaign audio logs and skulls question

Quick question

I missed a few skulls (in mission) and an audio log on my first run through. Do I have to find them all again when I replay the campaign? Trying to finish some achievements.

No, I think your collectibles and audio logs carry over. So if you get a skull you’ll still have all the ones you already got.

Only exception is Spartan Cores and the forerunner audio logs as they trigger campaign dialogue.
