If I connect an HDMI cable to my MacBook (mid-2010 white model, Mavericks 10.9.2) and play a video, then the audio comes out of the TV - so far so good.
If I then close the lid while the video is playing, the TV screen flickers a bit but then continues playing, but the audio starts coming out of the internal speakers.
Is there any way to stop this and force the MacBook to continue to play via the HDMI when that's the only screen in use?
Extra Info: re-opening the lid doesn't switch audio back to TV but all settings suggest the TV is the selected audio output device. If I pause the video, THEN switch to internal speakers and back to TV, audio will be back to TV if/when I restart the video playback.
