I have been playing music on my Macbook Pro using my headphone output to my stereo. However the mini jack inevitably goes bad within a couple of months and I am wondering if there is a better options? I was wondering if I can send audio out of my USB socket? With just a USB to phono? or am I dreaming? : ) If not do I need to buy an interface? Just want a simple cheap solution that wont crackle and go kaput after a couple of months.
