Hey everyone. I use my MBA to watch media on my tv and for a long time have used a MDP to HDMI cable that has worked great with my 2010 macbook pro, 2012 mini and up until recently with my 2011 macbook air (specs in sig). All the sudden it won't play any sound. I see the option for my TV in sound settings and have tried messing around a bit to get things to work as occasionally connectivity hurts it but now it's been about a week or so nothing has changed. Any ideas?
