I updated yesterday (it's iMovie 10.1.7). When I import a clip now, the latter half of the audio is missing. I tried tons of clips, exact same thing happens every time, also with ones that worked fine before the update.

Hmmmm. The other poster who had the same problem with 1/2 the audio missing was able to solve it by deleting preferences. But every computer is different.
Try opening iMovie in a new user account, such as the Guest account on your Mac.
If the problem persists, I would try re-downloading iMovie 10.1.7.

When I import the video file, only the first half of the audio is imported with it. If I convert that same video file (I used SmartConverter for that) to pure audio and no video (an mp3 file) and then import it to iMovie, I get all the audio, not just half.
So first I import the regular videoclip, that only gets half the audio (as you can see in the image, the waves go flat), and add it to the timeline.
I then import the mp3 file and add it underneath. It will sync up perfectly since it's the same file, only one is video and one is audio.
Then I will detach the audio from the videoclip.
Now I have both the pure mp3 file I converted earlier, and the damaged audio that only has half. I delete the bottom one, and the mp3 file now works in sync with my video.
This is all contingent on the mp3 file importing fully and not missing the last half like it does when it's attached to the video. Which it does, for some reason.
At the moment, the only solutions that I know of that have worked are 1) open iMovie while holding down the Option and Command keys and then delete preferences in the box that appears, and 2) Yasmin's solution of detaching the audio and re-importing the audio after importing the video clip into iMovie.
However, I just noticed that Yasmin's codec on the audio/video clip had an HE in its title, maybe referring to High Efficiency video, that is a new codec. That codec, HEVC, occurs by default when exporting a video from iPhone 7 or later. Possibly that is causing the issue of losing 1/2 the audio when importing into iMovie. Just speculating. If so, you would need to convert the vid into Mp4/AAC using the free download Handbrake or the free download VLC, or some other converter. Possibly you could just open it in Quicktime Player and then save it, and that would give you a .mov file that you can drag into iMovie.
Léonie's post in this thread explains how you can change your iPhone settings to record in the standard H.264 codec.
Photos was quiting - now won't play video

Apparently, I'm having the same issue. I presume, you have downloaded the video from facebook. The same video, if i download from Yoututbe , The audio is okay but when downloaded from Facebook, the half of the audio disappears in iMovie.
Hi, Rich! Thanks for answering. I tried it and deleted the preferences, but no change. I saw your second reply before you deleted it (came to my email). The codecs are H.264, MPEG-4 HE AAC. Also tried new projects, but still the same issue. I updated to High Sierra after posting this, but it didn't help my sound problem (it did help with the clips not being stuttery anymore though. They're pretty HD.).
I just tried it on a different account, no go. Also un-installed and re-downloaded it. No change 😟 Very frustrating. I now also have this issue: imovie not exporting video to file (error 10004) with most of them, and I never had those before either. Sigh.
Sorry. I deleted this because my response was intended for another poster.

Well done. Not sure I follow your work flow. Could you explain it in more detail?
-- Rich
Thanks for posting back your clear and detailed explanation. That will help others who may have your issue.

That's strange. But no, I haven't downloaded it from Facebook. It's from.. let's just say, elsewhere. lol
I've got the same problem and tried all the solutions proposed. Have not tried Yasmin's solutions yet, but it is not a single case problem.
And that only happens since the last update
Try restarting your computer and opening iMovie while holding down the Option and Command keys, and then selecting to delete preferences in the box that appears. Sometimes that cures glitches that occur after an update.

Came up with a sorta solution for the audio problem, albeit it's extra work. Detached audio from original clip when imported, deleted it. Converted a copy of the same clip to strictly audio (mp3). The whole thing gets imported when it's just the audio, not half when it's with the clip -- weird, but at least good in this situation. Put the mp3 under the clip and voila.
I have this problem too. Did you manage to get it fixed?
Half of audio missing after update
