I’ve mostly been very happy with my migration to Lion, but I did get bit with one bug after the upgrade: for the life of me, I couldn’t get sound to output through HDMI when using my Kanex Mini DisplayPort to HDMI Adapter. That meant the days of hooking my 11-inch MacBook Air to my 47-inch 1080p HDTV were at an end.
I wasn’t alone. Apple’s support communities are filled with threads from frustrated Lion upgraders who suddenly lost the ability to pump sound through their HTPCs. HDMI sound also stopped working on my girlfriend’s MacBook when she upgraded to Lion. It’s obviously a widespread problem.
Luckily, today I finally figured out how to fix the issue, and it was remarkably simple. Here’s how to get HDMI sound back into Lion.
I did something last weekend that I know many of you may have done already. I dragged my Mac Mini into the living room and connected it to my large screen LCD TV. I ran into an interesting problem after doing so. My Mac Mini would not display the Mac OS X menu bar. It wasn’t visible, but luckily there is an easy fix for this problem.
If you have a 27-inch iMac or 27-inch Apple LCD Cinema Display and you don’t already know about the Kanex XD, then you should. This miniature aluminum box enables you to take any device with a HDMI connection – such as your PlayStation 3, Xbox 360, or Blu-ray player – and hook it up to your iMac or Cinema Display via the Mini DisplayPort connector.
It’s perfect for casual gaming at your desk or catching a Blu-ray in your lunch hour, and it’s a great way to make the most out of your expensive Apple display.
