MacBook Pro (2018) Audio on videos cuts out randomly

I'm having the same issue. It's definitely not a browser situation because I've tested on several as well. I'm even coming across it on programs like Adobe Premiere and After Effects. I'm hoping it's just a patch in the next update.

No, not yet. I went to the apple store yesterday and they just decided to give me a new one on the premise that it's a hardware problem, but even the new one still has the same issue (way less frequent though). But I'm still in contact with Apple support. They now have the sysdiagnose results for both laptops, and I'm just waiting for the result of their investigation. Will let you know as soon as I hear back from them (probably Wednesday).

It could very much be! I'm not really sure what's going on yet. But I wanted to check if you had any other issues with it?
For me for example, when I restart the Mac and sign into my user account the animation is very glitchy. Also when I sign into my iCloud account to link it to the MacBook Pro, I receive an email saying that I've signed into a 13" MacBook Pro, even though I have the 15"!!

Well so far I've tried everything I could. Reseting PRAM, upgrading to Mojave, installing a fresh copy of High Sierra, running hardware diagnostic tool (no issues found), got a replacement MacBook Pro and still no fix! Will have to wait for the apple engineers to get back to me I guess. I'll let you guys know how it goes, but it might be a good idea if you contact them as well!

I have the same problem and I am guessing that the problem might have something todo with Apples new T2 Chip because it handles the audio.

Do you have "Hey Siri" enabled? Try disabling it. It may help the problem go away.

Would like to hear back if it works for you!

Interestingly enough, disabling Siri helped for me, at least for the past ~24 hours the problem did not occur again.
Then again, my speakers don't have any popping, so those two things might be different problems

I just disabled Siri as well and will report back on what happens.

Also someone from the AppleCare Help Desk just reached out to me yesterday and he's trying to find the root-cause of the problem. Sent him some more sysdiagnose data and will be waiting for his call back.

Thought i was the only one experiencing this. Setting up an appointment with the genius bar on wednesday. Hopefully we find a solution to this. If you guys do let me know. My theory is its a hardware problem.

A week since disabling "Hey Siri" (only that, not Siri in general) and the problem never occurred. Enabled Hey Siri again this morning and the problem started again. Pretty sure it is really the "Hey Siri" part that is responsible

I have the same issue. I've just disabled Hey Siri and will report back later if it solved my issue. If it does, not sure what to do about it. It seems like faulty hardware/design but given I got my laptop on launch day, it's a bit too late to "return" the device... Let's see if this test does work and if so, I'll chat with Apple Care folks and figure it out.

I just tried this and it worked for me. Why the heck would something like opening an incognito window work over resetting the dang NVRAM?! My mind is in shambles over this.

I have had my 2018 MacBook Pro 13" w/ Touch bar, 1TB, 16GB for one whole week now. What even is this!?!

I am also having this issue on my one week old 2018 13" macbook pro w/touchbar. I read some replies and tried the incognito window suggestion, which has worked so far. I have no clue why it helps, but I do recall having issues with google chromes "hardware acceleration" option, which is usually turned on by default. I would suggest turning that off to anyone who has google chrome installed on their MacBook, it may help and can reduce & avoid other weird bugs, like the shaking browser bug from a year or two ago.

I've been having this issue as well. I got it the 18th of August. I had issues with headphones, mbp speakers, as well as an external DAC (RME Babyface Pro). I got this machine to work on audio for work (15" i7, 16gb ram, 512gb ssd), I really need the dac to work flawlessly! I disabled "hey Siri", let's see if that works.

The same exact thing happened to me - I got my 2-week-old laptop switched out for a new one but it keeps happening. I have another appointment with the Genius Bar but I'm guessing it has to do with software, not hardware which I guess is a good thing... hope they fix it in an update soon.
