I have a 2012 Macbook Pro with a Micron 512 SSD and running High Sierra that works fine but will not chime. Everywhere I look online the "No chime" conversations are always accompanied with startup issues or the elementary issue of no knowing how to operate the sound preference pane. Neither of these are my issue.
The computer starts normally, just No chime.
Pram and smc reset do not help nor does disc repair.
I buy and sell Macbook Pros and use them extensively before selling them as I warranty and repair them as needed. Have been doing this for years and never seen this issue. I have seen some occasional strange boot behavior. Once in a great while the boot process will exhibit some aberrant behavior. One time it booted to the desktop and then returned to the Apple and progress bar before returning to the desktop. This was an isolated incident and almost always it boots properly. I just mention this as I wonder if the chime issue might be the harbinger of a GPU issue which is (as you veteran repair people know) the almost singular problem with Apple laptops.
