It is a stretch to suggest there is an inherent hardware issue producing "your" problem when you can't find any thing about it on the web when the total of intel Macs is hitting approximately 40 million at this time.
Just because you can find cases of individual electronic hardware dying or not working properly, does not indicate an inherent flaw. Except for the inherent flaw that is in all things man made. It's going to fail at some point in time. Some sooner than others. You start seeing 5-10%, or 2-4 million out of those 40 million units with the "identical" issue, now we're talking about something the engineers need to start looking at and we're talking about the inherent flaw theory.
Am not suggesting that there may not be something wrong with "your" Mac. If, the inputs on the amp work fine from other sources and using the same cable, then I would be looking the same place you are, at the Mac. The first thing I'd try would be to clean the headphone jack - power off and disconnected, battery removed if possible - take a can of air and try that - I might even try a q-tip dampened with alcohol on it if it were mine - making sure not to turn it back on until it dries thoroughly. Next step is going to be to call Apple, set up an appointment and take it in for them to have a look at it.
Nope, not meaning to sound condescending. Anyone that's been or begins purchasing electronics is going to end up with a drawer of extra cables. I have at least 4 or 5 such drawers that are full of cables collected over the last 40 years or so. With the cost of audio cables and adapters today, I just don't feel a lot of sympathy related to someone having an issue spending $2 or even $20 to attempt solving a problem. Well, maybe a little condescending after all, I admit.
I'm quite willing to work through the things you can try at home before taking it to Apple.
I am assuming here that you are using analog cabling at this point, because I can't see that digital could have the issue you'r describing.
Spending < $4 - one example
- just to see if it may solve your issue by simply switching to digital instead of analog, isn't too much to ask imho. "Assuming" that is, that your amp has digital inputs. And beyond that if it works, a toslink splitter
