I am having audio troubles. One channels went out, apple replaced audio and logic board. When I plug my headphones or JBL speaking I get good stable sound. However, when I plug into my older pioneer amp with a Monster splitting cable, sometimes I get sound other times none or when there is sound it dies after a while. Manipulating the plug-in headphone jock creates blasts but connect. I went to Best and the clerk plugin a new high end cable into a new AMP on the floor, but no sound. Has anybody experienced this.
