This has been a problem for me for a few months now, but it's just getting unbearable.
So, here's the situation:Oftentimes, my headphones give out muffled audio. It makes it virtually impossible to make out human speech, and just generally isn't very good. In the past, I could fix this by adjusting the headphone jack somewhat, but over time I've had to do it more violently and I'm concerned at this point that I'll harm the computer if I continue doing it. Now, whenever it happens, I have to wiggle the jack around with a decent amount of force to get it to work properly.
I'm not particularly good with computer hardware, so I'm not entirely sure what the exact issue could be. If you need any more information, just ask. I'd be happy to provide it. Any help is appreciated.
