Gofanco USB 3.0 to HDMI or DVI Video Graphics Card Adapter for Multiple Monitors w/Audio Up to 2560x1440 for Windows & Mac Systems Using DisplayLink Includes HDMI-to-DVI Converter Part (USB3HDMI) 4.2 out of 5 stars 215 $49.99$49.99 $79.99$79.99. All I see as possible outputs on the Mac sound preferences is the built in speakers and a list of Sonos speakers. (And, again, that was either not working or had a 2-3 second lag for sound.) Or maybe there's a way to create a fake HDMI audio device to just make the Mac send audio out through the HDMI cable? Choose Apple menu About This Mac. Click Overview, then click the System Report button. Open System Information for me. In the sidebar, below Hardware, select Audio. A list of your computer’s audio devices appears. If HDMI Output or HDMI/DisplayPort output is listed, your computer’s Mini DisplayPort can send audio. If you connect a Mac to an external monitor using HDMI or DisplayPort, you’ll often lose the volume controls on your keyboard. Depending on how you use your Mac, this can be kind of annoying.
