I have the option to select HDMI in all the aforementioned locations (the device is called "HDMI TV"), and, when chosen, sound is properly output via the AV receiver according to the source material (5.1 with both DTS and AC3 encodings work fine, as does stereo).ģ) As soon as the projector is turned on, video appears fine as expected on the projector, mirroring the MBP's screen, but the HDMI option disappears from all above lists of sound output devices. menu-bar shortcut and in Audio MIDI Setup and VLC Audio -> Audio Device submenu), but didn't work properly after wakeup.Ģ) With our issue, when everything is connected but the projector is turned off, sound works fine.

#How to airplay from mac to nvidea how to
I can't for the life of me figure out how to either:Ī) Disable Airplay in my Denon receiver OR more apropos to this forum,ī) Get HDMI restored as an option in my Sound Output preferences.

Now, whenever I try to connect through HDMI, I can only get the display to work. So there is no issue with my sound card not supporting HDMI. Prior to upgrading to Mavericks and numerous updates to my Apple TV, I was able to plug in to my Denon receiver via HDMI and get display and sound options pop up through System Preferences, no problem.
