Question

Crackling sound, but only when a sound effect comes on while music is playing

Hi, I've bought less than a week ago a 15" Macbook Pro, everything is fine except for the speakers.

I have already read a lot of posts online of people complaining their speakers had bad crackling problems. However, I have found nothing that describes my situation.

Shortly, if I'm listening to music and a sound effect comes on, the speakers make a single crackling sound, like a 'pop' or something. This happens both with notifications and system sounds, and when I'm listening through my earphones everything is fine. I also tried muting system sounds, but the 'pop' is there, even if the sound isn't actually coming out of the speakers. However, if a system sound comes on when I'm not listening to music, there's no problem. I also tried killing the 'coreaudiod' process, tried changing the Hz from the Midi-audio app, but it didn't solve anything.

At this point I think the problem is the combination of music and system sounds.

I hope this can help Apple fixing this bug. I'm pretty disappointed that a 3400€ machine has such a problem, that hasn't been resolved in months judging from the feedbacks of the other users.

Also, if anyone has suggestions or something to add, please tell me. I think that in the end only an update can solve the , but in the meantime every help is appreciated.

Thanks,

Giovanni

MacBook Pro w/ Touch Bar (2018 or later)

Not certain if you could get noticeable result or improvement through one or both

of these 're-set' Support articles. ~ Their instructions may need repeats for full effect.

The main reset is somewhat like a general one, includes power management reset:

They're some things one can try to resolve an issue; part of routine troubleshooting.

If you try these, nothing untoward will happen to the Mac. They are not destructive.

However if not properly applied, nothing may happen at all; or to say 'no effect'.

For further information you may contact Apple (or authorized support) via reservation

If you've an extended AppleCare plan, another route to consider would be inspection and

hope their technical expert could find something in hardware that may be a cause of this.

Even items outside the initial one-year coverage may be given consideration and tested

for hardware failure via the Genius bar or other authorized service; and options given to

provide closure to an issue where either the product hardware &/or software is a cause.

If you have a complete backup of your content, perhaps even in addition, a full system clone

this would then allow any repair service (or you) to totally erase the computer to see if a new

system installation may help resolve the symptom(s). ~ There may/or not be faults inside.

To try a second admin-user account for troubleshooting may help narrow focus in this matter.

Sorry to not have a magic answer; except for genius bar & official authorized support/repair -

outside of suggested possible system resets perhaps 'hardware tests' ~ looking for a solution.

For now I hope the problem will be solved via a future update.

If that isn't the case, I'll send it in for an inspection.

Of course I know you don't have a magic answer!

I still appreciate your help nonetheless.

Thank you (:

I use iTunes and Safari (Youtube, Bandcamp, online radios) but the problem appears with both of them.

Right now, the problem seems to be gone, so I can't tell you if another player would work correctly.

Are there some risks doing this? Or am i going to lose something?

Sorry, I've never heard of these resets so I want to be sure before trying them.

Hi,

sorry for the late reply.

I tried both methods, more than once, but the problem is still there.
