Audio Jack Issue
I got a new 12 core Mac Pro about a month ago. Purchased with two Cinema Displays. Last week I bought some speakers and only the left speaker is was putting out sound. I thought maybe I had a bad set with a short so I returned it and bought a new different brand. They worked for a day or so and now the right speaker isn't working. Anyone else having audio issue? Any ideas on maybe if I have some settings messed up or something. I'm getting really annoyed. I'mm a proessional editor and I need my speakers to work.
Mac Pro, OS X Mountain Lion (10.8.3)
