Loss of sound in iTunes on my MacBook
Ok, some of you may have seen my confusing posts regarding loss of sound in iTunes on my MacBook?
So I'm guessing by the silence nobody likes me or, maybe you need a little more info?
I'm old & probably using the wrong words, so bear with me
Fairly confident the amplifier + speakers still function. (Thank-you Apple)
The media itself is in working order.
So,
The file/process that decodes/reads Boot/Start Up sound file is 100% reliable.
The file/process that decodes/reads notification "aiff" files operating around 68%.
The file/process that decodes/reads media "m4a" files is barely working at all.
if it's just these files or some file in-between, surely there's a way to replace/renew ???
Could I reset this process or maybe the system??
What if I sold this laptop back to myself? Would that start afresh?
Probably clicked on a bad protocol while using Safari...
Perhaps a recent amendment/update in sound protocol affects only this run of Laptops: So that Chinese chip on the circuitboard made in Taiwan will no-longer function..
Or have I unknowingly violated Apple protocol & this is my eternal punishment (Should have looked closer at paragraph 42 in the Terms & Conditions of The User Agreement on page 537)= Thou shalt not listen to thine iTunes while browsing thy FaceBook.
Taking all this into careful consideration & the fact that I bought "this" my #1st Apple (second hand) & started using the internet in 2021, it's most likely all my fault but how do I fix it?
Possibly takes someone younger than this MacBook to decipher my problem? (God help me)
