Just another little oddity with the headphone jack; I had the same issue but the above fix didn’t work. I had to make sure my head phones were plugged in when I powered it on to make sure they worked. If I plug them in when it’s already on they sound terrible. Maybe the headphone? I have Audio Technics pretty nice headphones and they work on everything else perfectly. So clean. Anyways just though I’d share in case this doesn’t work for everyone. Cheers.
