HDMI Audio Output Still Not Working? Check the Mac for HDMI Sound SupportĪlmost all new Macs support audio over HDMI, and practically anything newer than a 2010 model year will have native support. This does not mean that exporting sound is not working, it simply means that sound volume must be controlled through the hardware the Mac is now outputting to through HDMI, which is typically a TV or presentation shooter, as the internal volume adjustment sliders and keyboard buttons will no longer work. You will notice that after an HDMI sound output source (and many other output options) has been selected, the Sound menu icon turns grey: Going the other way, this menu trick will also let you change input sources as well, making it easy to toggle input from an external microphone, another audio source, or back to the default internal mic as well. Switching back to the default audio source (typically the internal speakers or sound port) can be done by again Option+Clicking the sound menu icon and then choosing “Internal Speakers” from the pulldown. Of course it’s still possible to use the other method of going through System Preferences > Output to control this, but since it can all be done from anywhere without launching into settings there is little reason to go that route. Though we’re focusing on HDMI here, this will apply to all other means of exporting audio as well, including apps like WavTap that capture all sound. Play a sound effect or any form of audio to confirm it is working. The change is immediate, and the set audio output destination will have a checkbox next to it’s name. Find the desired audio output destination under “Output Device” and select it from the pull-down menu.Hold down the Option key and click the Sound icon.
