Hi, I'm new to the forum but have been reading MacRumors for a while now. I have just bought an Apple TV 4 and want to use my Apple TV 3 it has replaced to stream music to in another room. I have an HDMI to VGA adapter which has a 3.5mm jack for the audio and wanted to use that to get the job done. I used a computer monitor to set up the ATV3, plugged my sound dock into the HDMI to VGA device with a 3.5mm audio cable. I played some music on my iPhone and switched on AirPlay. Everything was working great until I unplugged the VGA cable and the audio cut out and would only play when the monitor was plugged in. Unless I am missing something in the settings it seems I cannot have audio output through the HDMI without a display on the other end. Is there a way I can get the audio output from the HDMI without a TV or monitor connected or alter the VGA cable/connector to fool the ATV that a display is connected? Any help would be appreciated.
