If the Clover HDMI method is not working fo you (it didn't for me) try installing AppleALC instead which supports Nvdia HDMI Audio ... you can use it alongside an existing AppleHDA enabler if your analogue/codec audio is already working.

AppleALC is also a HDMI audio enabling method described in Toleda's HDMI guide post #2 ..... see the workarounds section, step 3, check to see if your Nvidia cards GPU is already supported (I suspect it is) if it is then there is no need to use Xcode. just remove the previous method patches and install Lilu & AppleALC and see if it works, it worked for me with Nvidia 980 Ti.
