MProbably an intolerant resistor or chip with inadequate tolerances. Might be solder.
That's not how logic boards are made in 2018.
Stop speculating. It looks really silly. Contact Apple or return your machine if you're not happy and wait for news.

They ARE made that way, but they don’t have the amount of solid state parts they used to use. The size is now tiny, as well.That's not how logic boards are made in 2018.

Check if your speakers hiss, too. Just go into the Sound settings and play the alerts.I have not had the cracking issue, but I now notice that I get pops when muting and unmuting in iTunes/Apple Music and YouTube. It will do it a couple of times softly, then loudly, then not at all.

Strictly speaking there is no more separate SMC in new Macs (see System Info app). It has been integrated inside the T2 with the other controllers.
Apple shows how to reset the "SMC" in T2 Macs. It's not the same method as older systems. So in case you are using the old method, try the new one.

But I say this will have limited effect until new firmware and drivers are done.
Is Apple saying it is a hardware issue? Looking through this thread, the general suggestion seems to be that it is likely a software issue. But Apple do seem to be sending out a lot of returns. Does anyone have any direct information from Apple on whether it's software or hardware, or does anyone have specialised knowledge on this?
Personally, I have the crackling, but only experience it on Boot Camp after running Civilization VI for about a half hour. I did not test extensively on Mac OS though. I'm planning on waiting for Mojave and new Boot Camp drivers or new firmware to see if this is fixed by software. If it isn't, I will return it for a replacement under Australian consumer law.
The eacalated support manager who dealt with my case said Apple is aware of this issue, it is a hardware issue and does not effect all units.
Appreciate this advice man. good to hear this but tell me something , Do you think this is a corrupt time machine causing this or is it an apple issue ?

and after even a restart the volume doesn't came up at the normal volume?My 2018 15"/512/16 speaker just reduced to half the volume at maximum after a few high pitched noise while watching youtube. Prior to this there were loud pops whenever I click different time line in youtube (70% ish). I was going to return it anyways so I don't care so much. But what a disappointment.
have had this second 2018 15'' i7 MBP for a week now
with the first...I installed Logic Pro x and only saw issues thereafter...the crackling started in youtube videos around 43mins into a video like clockwork.
Logic Pro x changes audio midi output from 48 000 to 44 100...
this is definitely the issue
at least for me
because
I got the second and checked the audio midi settings
default was 48 000 for the output
computer was fine...apart from small choking hiccupy-ness??? when pausing stating skipping through video
THEN I installed Logic Pro x on the new computer...and worked for a while and quit Logic Pro x
checked audio midi settings...
it had automatically changed to 44 100...I left it at that
later I experienced the crackling while watching a you tube video at around 50mins in...
changed audio midi back to 48 000 and have not had problems with 48 000...not once in a week
but with audio midi output at 44 100 its problems it seems...
so I've got the audio midi settings applications in my dock for now switching between 48 000 for recreational viewing listening
and 44 100 for work in Logic Pro x
anyone willing to give this a test on their machine?
the default is/was 48 000 output
seems fine
44 100 is where the crackling happens...after leaving a long stream or podcast on...45mins in the crackling will start if the computer us just left to play media
might be a power output issue at certain sample rates...??? I don't know
very very disappointed thats all
same here...since i am on 48, no issues, thats why i think its 99% soft audio setup issue
Apple should remove 44 entirely ?
So if you play youtube or itunes for 1 hour the speakers begin to have issues all the time or just 1 crack ? i mean you hear 1 issue every 50 min ? Or after 50 min you can no longer listen?I just spoke to Apple support for the second time after testing the audio on a new test user account. Predictably, exact same issue - audio crackling after ~50 mins of any app playing audio.
I'm already in the middle of a work project so I can't return the machine for at least the next month, but the guy assured me I have a year under warranty so no sweat at this point. I figure I'll wait it out till we have an official answer on what's going on. In the meantime I use an external audio interface for work so I can live with it.
But yeah, disappointed that my £2700 laptop isn't up to basic operating standards. And it's kind of unbelievable that this issue seems to affect the majority of units and got through product testing...
For me, after about 50 minutes the crackling begins, happens every few seconds, sometimes it repeats the same short chunks of audio. If I close the web browser or iTunes and relaunch then it's fine again for another 50 minutes.So if you play youtube or itunes for 1 hour the speakers begin to have issues all the time or just 1 crack ? i mean you hear 1 issue every 50 min ?
