So i just bought a pair of audio monitors. I connected them in my m-audio solo but the sound does not come out. I already checked for updated drivers, selected the m-audio as audio unit, i did everything but nothing comes out from the speakers. The m-audio works fine, it receives the signal, I always record with it. Strange thing is that everything works fine on other MacBooks.
I have a 2010 white MacBook with Mavericks 10.9.5 installed
MacBook, OS X Mavericks (10.9.5)
