I currently have the 11.6 Macbook Air. Base specs. I have a Samsung LN32C450. I'm using this: Mini DP to HDMI Adapter and HDMI Cable When i first plugged it in, the sound transfers to my tv. now whenever i plug it in no sound goes through. I go to sounds in my preferences, it says "The selected device has no output controls." it reads SAMSUNG HDMI. how can i fix this?
