    Audio problem (Dolby TrueHD and DTS-HD at 1080p60)

    alfrix

      Intel HD4600 (4790k)

      Windows 10 pro x64 10.0.10586

      Driver from WU 20.19.15.4331

      Denon AVR-591 (hdmi 1.4)

      Dell 2709w

       

      The connection goes like this

      PC > HDMI > Receiver > HDMI > Monitor

       

      My question is:

       

      Is it possible to pass-through (bitstream) HD audio like DTS-HD and TrueHD at higher resolutions that 1080p50 or i'm missing something ? it's a driver or bandwith limitation problem?

       

       

       

      It seems odd that i can pass-through DTS-HD and Dolby TrueHD at 1080p50 but not at 1080p60, tried a lot of drivers, but always had the same results.

       

      Furthermore, the monitor its 1920x1200 but at that resolution i can't pass-through the HD audio modes

       

      To by pass this problem, i have connected:

      PC > HDMI > Receiver > HDMI > Monitor

      PC > DVI > Monitor

       

      Then configured DVI as Main input at 1200p60 and HDMI as Secondary at 1080p50, this way i can bitstream HD audio and use the full resolution of my monitor.

       

      Note that I can bitstream DTS and Dolby digital without problems at any resolution mode, and always have the HDCP marked as compatible.
