I also get the chime and 'power connected' sound sometimes, and it's not muffled as well. -

yeah, I'm still dealing with the same thing, I started using headphones until I have headspace to tinker with the audio chip or something, because no amount of reinstalling anything helped.
The audio returns sometimes before I log in, but it's muffled as if the speaker is blown, which is not true since I'd replaced them.
please share if you happen to find the culprit before I do....Leave a comment:

Thank you for such a fast reply! I'm not entirely sure though how do you mean. You mean reinstall OS?Leave a comment:

All right it took me a while but reporting back.
I've swapped the speakers, the issue persists.
The weird thing is -- until the OS is fully loaded, the sound is present (chime, charging sound etc.) but once the OS is loaded, it disappears and is only present in 3.5mm headphones.
What could this be?Leave a comment:

Thank you, appreciate it. What I meant is, I bought it new, it's not new anymore
I'll swap the speakers, will update this thread.

Thank you! Yeah, I'm waiting for a new set of speakers. It was bought new, it's my machine, I'm not an electrical engineer, but have fixed many laptops and phones for myself, friends etc. so I have some experience. I'll try replacing speakers, but just out of curiousity, what's the audio chip called on these?

Forgot to mention -- the sound is present in the 3.5mm headphones, no distortions.Leave a comment:

Apple MacBook Pro 13 2020 Intel silicone 820-01949-A A2251 no sound
Hi guys, I hope you can help me. I'm trying to identify an audio chip on this device, since NVRAM reset, SMC reset and replacing speakers yield no results, I'm pretty sure it's the chip. The sound comes back briefly after [I]sudo killall coreaudiod [/I]but it's muffled, as if the speakers are blown, which they are not. Same effect with SMC reset -- the sound comes back briefly, sometimes the chime can be heard, sometimes it's absent.
I have a schematic for the Open Board View, but I can't seem to locate what is usually an audio - U6200 or U6201, what am I doing wrong?Hi guys, I hopeLast edited by koinoyokan; 02-17-2024, 09:01 PM.
