Audio not present on video capture

  • Question
  • Updated 1 week ago
macOS Mojave 10.14
MacBook Pro 15" 2018
Chrome Version 70.0.3538.77 (Official Build) (64-bit)
Snagit Version 2019.0.0 (94003)  and Version 4.1.10 (78127)

Started with Version 4.1.10 this morning.
Open Chrome
Open Snagit
Set Snagit for video capture the Chrome window
Record video but observe that no audio is captured in Snagit editor
Fiddle with Snagit controls and retry 10 times
Google for help
Check for Snagit updates
New update available for purchase
Purchase Snagit 2019 and install
Return to Techsmith site to fetch software key and install.
Try capture again
Same results, video but not audio.
Try saving capture as mp4 anyway and playback from alternate video player
Try capture again. Noting that the green microphone icon/area/control at the bottom of the capture screen is active...I note a horizontal indicator moving in concert with my voice like a VU meter might.
Record again "test test test," I say
Playback in editor and observe again there is no audio.
Save as mp4 again...no audio.
Google the problem some more
Go to YouTube and play a video at random to make sure audio in computer works. Audio works fine.
Look at clock...realize that my simple task of this morning, to record a 1 minute video has now gone past an hour.
Note uptick in agitation level. Begin vocalizing the very bad words that have been forming in my head over the past 45 minutes or so. The raving voices begin...why is it so often like this with technology...John Steinbeck wrote "The Grapes of Wrath" on yellow legal pads with #2 pencils...never had to check for new version of pad, or fiddle with privacy settings of pencil. Vow to just abandon all technology, move to Katmandu and study with the monks. 
Seek help.

So what is preventing the capture of audio from my built-in MacBook Pro microphone? How may we solve this problem together, in the spirit of cooperation, community and advanced levels of technical wizardry?

Jeff, that looks incredibly frustrating!  But you did a great job of documenting your troubleshooting attempts.  I'm sure TechSmith will appreciate that.

I just had one thought.  Have you tried recording a video with sound using QuickTimePlayer, just to rule out any issues with your mic or sound setup?

Jeff, unfortunately, I've got nothing helpful to offer.  I just wanted to let you know that that's the best troubleshooting issue I've ever read.  My heart goes out to ya.

Didn't know I could record with Quicktime Player. I tried that and...no audio. Great. TechSmith, I guess you're off the hook and I will have to take my issue to the Apple forums. Have you ever been to the Apple forums? Awful...

Thank you for your help.

Oh no wait. Maybe I won't have to subject myself to the Apple forums after all. So a Quicktime Player "Screen Recording" apparently doesn't record audio. I can make a Quicktime Player audio recording and it works just fine.

Actually, it will.  You just need to select a mic:



I just did a QTP Screen Recording with mic and it captured my mic perfectly.

Ah yes, I see that. Thank you. I selected the mic and it worked fine. so I can record screen and audio with Quicktime. I went back to snagit and checked to make sure the mic was selected there. It was. Tried another recording and it still looks like it's got audio available (the little green VU meter bounces when I speak) but resulting video has o audio when played back in the snagit editor.

Just by the way of updates, I've also uninstalled the previous version of Snagit, restarted the computer, and found where the mic share settings are in the privacy settings and double checked that both Quicktime and Snagit are authorized to use the mic.

Hi Jeff,
While I feel your frustration and realise you must be heading towards 4hrs to do a one minute grab was wondering if you could pull the video in to a video editor that shows the audio track separately and increase its gain. Then look at the video track to see if it has any peaks and troughs. If it does it might be either a head phone and mic is plugged in our the volume level is extremely low.
I realise this seems far too much work for such a simple project but thought it worth putting it out there.
If you don't have those tools im happy to check the file for you just upload it to a public storage area.
Can look at it in the next 30mins or much later in about 16hrs.
Enjoyed your first post. Many little jobs not just on computers have turned in to epics for me lately

Someone else had a reply here suggesting changing mics, but I don't see it now (must have deleted it?).

I have USB headset that I tried. After plugging it in, in the Snagit capture options I can choose between it and the built-in mic. It works! I experimented around a little with curious results. The headset has a mute switch on the cord. If I record and flick the mute on and off, I can clearly hear that the audio cuts on and off. If I mute it, but then select the Mac internal mic, the mac internal mic works. If I unplug the muted headset, the mac internal mic doesn't work anymore. Weird. I went into the mic settings and tried adjusting the mic sensitivity/volume up and down and retried recording with only the internal mic. Made no difference.

So the only way I can get the internal mic working so far is to plug in an external mic and mute it. But maybe if I have the headset plugged in but not selected the mute switch doesn't work and what I'm hearing is actually the external mic even though it's not selected and is muted? 

Time for some technology avoidance therapy. Back soon.

That was me that removed  the comment. You got QuickTime to record your mic and I'm a Windows user so I really don't have much business throwing in my two cents.
My input is flawed in most cases.Try another mic is universal, I was comfortable with that.LOL

Maybe SnagIt thinks your mic is a webcam mic for some strange reason. So without a webcam turned on, its not picking it up.Or some other strange explanation.

I know how to go into a Windows machine and set up any microphone I want as the default recording device. That would be my first move in your situation.Making sure its selected as the default device.
I would imagine MAC's have similar controls?

Anyway, good luck with it. Theres always tech support come Monday.

Hi there

I'm not a Mac person. But I watch these threads and in the past I think I've seen some on the Mac side recommend this thing called "Sound flower". Maybe it's worth a shot?

Cheers... Rick :)

The Video Capture in SnagIt  doesn't allow Sound. Never has.  Camtasia Though does allow Sound, But when first installed and opened you must give it permission to use microphone.

That is incorrect.  SnagIT video capture DOES allow sound.  Here's the toolbar ready to record video.

Looks also like the Speaker icon (if clicked) allows capturing System Sounds too?

As long as I used SnagIt the application before it I've never been able to record audio even setting system to recognize internal Mac  or Sound Flower.

@pjonesCET, I have no idea why it doesn't work for you, but it works perfectly for me.
I just recorded this using Snagit 2018 2018.2.3 (90456) on macOS 10.12.6:
