HP ProBook 4540s no HDMI Audio

[shinsukemura]

I’ve searched for ways to make the HDMI audio work, through DSDT, VoodooHDA, individually installing audio kexts. Nothing has seemed to work so far, my hopes were on DSDT patching (Toleda’s HDMI audio editing), but I have noticed even though the HD4000 Toleda has specifies for socket 1155. CPU-Z says that mine is Socket 1023. Overtime I try patching it with Toleda’s; I get errors. If there is a way to help my case, I would be extremely thankful. Thank you for your time and hard work.
