So, I've received my second MBP15 TB (first one was replaced cuz of keyboard issues) about 1.5 week ago. Usually I use mbp with my headphones, but today I tried to listen music through internal speakers and found out that left speaker doesn't work properly. It has significantly lower value and actually sounds awful. I've checked preferences and audio midi setup, all is well. Before this I was disappointed with my mbp, cuz I was waiting for 1.5 month for replacement (laptop is my main working tool). Now I hate it. Apple rly? Tomorrow going to the service center -_- Anyone else with the same issue?
