Before Chimera 2.2 I was using only the discrete GTX650, and all my three displays had audio (1 via HDMI and 2 via DVI). This was achieved via pjalm's DSDT patches for my mobo.With the release of Chimera 2.2 I started my journey towards enabling both HD4000 and GTX650 with HDMI audio (on both adapters). I'm using a Z77X-UD5H (HD4000) plus discrete Nvidia GTX 650). The whole thing works great via "IGPEnabler=Yes" and "GraphicsEnabler=No".The only problem is HDMI audio via HD4000. I'm getting audio on the discrete GTX650 (two displays via DVI), but via HD4000 (HDMI) there is no audio signal. I've tried several ways of compiling my DSDT with pjalm's patches (AIO+HD4000+discrete, AIO+discrete+HD4000…), but none has enabled audio over HD4000.Now I'm wondering if changing the port configuration could help with HDMI audio on the HD4000.Is it a trial and error process? Should I always need a DSDT to enable HDMI audio over the HD4000? Or just the right port configuration is enough for enabling HDMI audio?My guess is that I should use the IDs starting with 0166 (the ones for HD4000). Am I right on that?Thanks for this and the rest of wonderful tools !
