Alright, before the grumpy members of this forum start telling me to search Google and the Forum for answers, pause. I've already searched high and low for a solution to this issue but to no avail found nothing. Here's the deal, I've have my rMBA plugged into my TV via HDMI with the audio settings on my computer showing the TV as the audio destination but no audio is heard. (This seems to be the case with many rMBP owners but let's continue) I checked the settings on the TV and after fiddling with different settings (on the TV and Mac) still got no sound. I unplugged the HDMI and plugged it back in a few times (both with the TV and with my Mac). Still nothing. Now I thought maybe it was an issue with the TV not supporting HDMI audio-in but that's not the case either because my Xbox 360 runs via HDMI into the TV and audio works just fine. Seeing how none of the posts on this forum or apple's support forum seemed to help I did one last thing. I ran my computer through HDMI input 2 on the TV and ran audio out via a stereo mini cable into the back of the TV. The audio worked but it was coming through on the wrong channel which makes since seeing how the audio input on the TV is for HDMI 1. Now here's the kicker, when I switched my Mac back to HDMI 1 the audio being played through the stereo mini input turned off. It's as if the TV knows the audio should be coming from the HDMI but it's not. WTF? Is this an OS bug?
