no sound from right speaker and poor sound from left speaker
My right speaker is not putting out sound. The left speaker is working but sounds very tinny. I am guessing the subwoofer is not working either as the sound is so thin. I tried replacing right and left speakers and the subwoofer, but everything is the same. The connections all seemed to be secure.
I don't think it is a software issue. I have tried many things including resetting the SMC and PRAM. The problem is the same whether I boot into OS 10.6.8 or OS 11.
Is dit een goede vraag?
