Fix the HDMI audio output of GeForce 210 ( Tested on 10.11.3 stable) . The HDMI output works and also the analog outputs of logic board work as well.
Installation instructions worked for me:
1)Install both kexts on S/L/E and rebuild kext cache with kext wizard or MTH
3)Go to system preferences/sound and select the second HDMI output (is the only will work) or select analog outputs e.g. for headphones.
Thanks to MacPeete for patched AppleHDA.kext & to zzombiesniperz for the patched voodooHDA.kext
