MacBook Pro (2018) Audio on videos cuts out randomly

I bought the all-new 2018 MacBook Pro (13 inch, touchbar, 256 gb) yesterday and have been having issues since. While streaming video, every 5-15 minutes the audio of the video will cut out but the video will continue to play. If I stop the video and refresh the page, the video does not play. If I stop the video, wait about a minute, then refresh the page, the video plays with sound again.


This has been happening on Netflix, Hulu, and YouTube so it is not a problem with the site itself. I have reset my Wifi and router and have not experienced this problem from my iPhone, so I don't believe that that is the issue either.


Any thoughts? It's disappointing that this is happening when this computer is so new.

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.6)

I got the 15 inch (i9, 32GB RAM, 1 TB SSD)one and having the same problem.


Done some basic testing and these are my findings:

1. It's not specific to any browser (Tested on Safari and Chrome, in safari the video stops for a second and then returns but the sound takes a few seconds more and comes back as well. In chrome though if the video stopped once it won't resume!! refreshing the page also won't help! need to open a totally new tap for it to work properly again).


2. It's not browser specific (Same problem happens on Quicktime as well).


3. Tested with iTunes (audio only) and it still happens. It's more subtle but is still there.


4. It happens on both Mojave and high Sierra.


I tried to reset the audio system by doing:

1. reseting coreAudio by typing: "sudo killall coreaudiod" in terminal

2. Reset PRAM & SMC


Didn't fix anything though ....

If anyone has any input

I have a similar issue, which use to occur intermittently, but now seems to happen daily. When I try to watch a YouTube video or play an audio file, the sound is garbled. For example, I try to play a song from iTunes or Google music, and the sound appears to fast forward to the end. It happens across all browsers as well, so it's not a localized problem. Rebooting my computer clears it up temporarily, but usually by the next morning it happens again, and I have to reboot my MacBook yet again. Very annoying.

I'm having issues with audio drops on my new Mac mini running 10.14.1. I am an audio engineer and this issue seems to translate into my recorded audio as well as general audio output. What you're talking about seems to be related to my issue. My dropouts are 1 second at most and happen while listening to audio across the board (Safari, Logic, Spotify). Granted I am using an external audio interface (Lynx Aurora 8 via usb). I assume the problem is happening because my hardware isn't interfacing correctly or there is a Mac system issue. It's really tough for me to isolate the problem and monitor through the mini's audio D/A converter since most of my work is based around the I/O of the external audio interface.


Do you have any more information on avoiding coreaudio overload?

Hi,




Recently, I’ve started having the same problem on my oldschool MBP 17" Early-2011


i7 2,2GHz


16GB RAM


regular HDD 750GB


Mac OS SIERRA 10.12.6 (not High Sierra!)


Safari 12.0.2 (12606.3.4.1.4)




Precisely, audio cuts out while playing video in a browser (Safari) with no dependence on whether I open it in a regular or Private Browsing window.


I’ve set entire Siri to Disabled.


A reboot seems to fix off-browser video playback (i.e. in MPV), but not the browser video playback issues.


I don’t experience any cut outs in Youtube, but other streaming services are affected.


It seems the issue is related to a recent macOS security update, Safari or Flash/Java update - but I haven’t tried a rollback yet.


What I noticed is that when audio is cut out during video playback, I can’t bring the volume up or down and I’ve got a regular gray sound level square temporarily displayed, but with a small crossed circle (unavailable?)

Same issue, MacOS Mojave 10.14.2, MacBook Pro 15-inch 2018, ...

Main use of my macbook is for producing music (with Ableton live) and playing live, so a cut in audio is not a possibility!


I found a workaround: turn off the Wifi. When Wifi is turned off, I never experience audio cuts. This works for playing live, as I don't need network access in this case. But it's definitively not a solution in most normal cases!

I've also been having this problem, for about a year now.


I'm on an iMac 2017, 32GB, 3.5 GHZ i5.


Mojave 10.14.2


It really is annoying - there are various workarounds, but why should we be having to do this?


Sometimes the only solution is, for example if pressing stop on a youtube video also stops everything else (such as iTunes) - to turn down the sound (but not press stop) on that video. Or equally just turn the sound down on iTunes so other apps can run sound.


I'm running High Sierra Media Key Enabler which does help to some extent, but it's still as buggy as....deeply annoying, particularly because I edit sound and video in various packages, and often lose track of what exactly I have to turn down or

off to get the sound running properly - I can't believe Apple have taken so long to look into this, considering the time span of the issue, which seems to be relatively widespread. Help!!

Don't know if this will help anyone or if it's the same issue. After a period of sleep video (many sources and if one isn't working the rest aren't working) and audio (iTunes) won't stream. Video looks like it's buffering and I get a message that if the video doesn't start to play restart your machine. After a restart all works well. I've searched and found someone indicating audio out will sometimes lock and when it locks videos won't play. This advice was specific to speakers using USB interface, but I don't know if it happens to other output. I happen to have speakers connected via USB. So after sleep I get buffering, as soon as I change the output video starts without restart. I've not figured out how to stop this behavior, but I can at least jump into preferences and get going again without a restart. I know this is an old thread. Don't know if this is the problem for most of you, but something that's easy to try.
