Should I try multibeast now? Or maybe just wait for the next multibeast update?

Thank you so much toleda! HDMI Audio works (after setting all dsdt fixes to no, I already used a patched DSDT,) but only with the macOS default kexts (com.apple.nvidia.driver.GK100Hal, with com.apple.nvidia.driver.GK100HalWeb HDMI Audio appears but does not work. I am lucky as I have Kepler, the last OS X default-nvidia supported architecture) It seems like this is a common issue. Since I am not too worried about performance, and Macs have shipped with GT 650m and GTX 780m (780m has about as much performance as GTX 760 desktop) I am not too worried about losing optimizations. However, it would be nice to know if it is possible to get audio to work with web drivers. Based on some quick research it appears that the answer is no, but if there's a reason why, then maybe that could help us understand. Thank you again.

For Headphones, yes.
Another HDMI audio suggestion, enable HD630 HDMI audio.

dsdt has no Nvidia HDMI audio patches.
IGPU patch has nothing to do with HDMI audio, enables GPU PM only

Based on some quick research it appears that the answer is no

Research is not correct. With WEB driver loaded, see Post #1/Problem Reporting; attach all requested files

How do I enable HD630?

How do I enable HD630?

BIOS, you had to disable HD630; set to enabled.

Where in bios do I find it? I don't see it.

Off topic.

No. A DP2HDMI adapter is a better band aid.

Got a DP2HDMI cable, connected the HDMI end to the TV, DP to the machine but still no sound
