Could someone who connects their MBA to an external TV screen via HDMI check something for me?
Hook your MBA up to your TV via a miniDisplay Port-to-HDMI cable or adaptor. In System Preferences->Audio, select your TV as the destination for audio output. If you have a compliant cable, audio should now be transmitted to your TV speakers along with the image.
Now, by having an external mouse/trackpad/keyboard paired to the MBA, close the lid so you're in clamshell mode. You'll probably get a very brief blue screen on your TV before the image comes back.
Now check: is audio still being transmitted to the TV as well as video?
If you can check this, then thanks for trying and letting me know. I want to find out if I have a bad cable or if it's a driver issue or what, as audio stops being transmitted when I close the lid. FWIW I'm on 10.7.4, and it's a late-2012 MBA 13" (8 GB, 2 GHz i7)
