cracking sound and popping before 12.0.1 update

I just bought at bet buy an MacBook Pro (16-inch, 2019) 
16 GB ram 1 TB.

After updating the sisem 12.0.1 the left speaker sounds broken and just before updating I 
was listening to music in a normal way without strange sounds.

I need to know how I can proceed to resolve this issue since apparently it already happened 
with macos catalina

Hello, I have followed those steps and I have not had improvement in the audio. The sound 
from the left speaker makes a bass noise just like the speaker was broken.

this is the issue:

With any application or music the vibration is perceived and in the same way even when turning
on the computer with the startup sound it is perceived.


what should I do? Is it a new computer that i has payed $ 3,000 and has not lasted a month
working well?

Hello, Toto_Quezada.


Thanks for posting in Apple Support Communities. We understand that the audio from your MacBook Pro is not working as expected after updating macOS.


Is this only occurring in a specific app? Try testing in another app to see if the issue occurs elsewhere.


We also recommend a reset of the NVRAM:

Let us know how it goes! Take care.
