    Audio over HDMI problem

      Welcome

       

       

      I would like to report the followin issue with some drivers/funcions under Windows 10. After turning Hyper-V on the AC3 bitstreaming over HDMI (Dolby Digital) stops working. The PCM sound/audio and DTS bitstreaming are working fine/correctly in both cases - when Hyper-V is turned on and off, while AC3 bitstreaming works only with Hyper-V turned off.

       

       

      The problem occured already under the first release of Windows 10 and I think it applies to all drivers which appeared so far.

      Additionally, when you start playing a movie some parts of the screen are rendered as a kind of white semi transparent pixelated areas.
