    HD4000 no HDMI audio device with CSM disabled

    deepsea00

      Asrock Z77 Extreme 3, latest BIOS

      i7 3770

      Windows 8.1 x64

      Secure boot, UEFI mode, CSM disabled (using UEFI GOP mode due to dedicated R9 280X with fully UEFI GOP compatible BIOS)

      All latest drivers

       

      If I disable CSM - my TV is not appearing on my HDMI audio playback devices. When I enable it - everything is OK.

       

      If I recall - this wasn't happening on Windows 7.

       

      I see this (same issue) was already been mentioned:

       

      HD4000 no HMDI Audio with UEFI GOP

       

      Any chance of fixing this issue?
