I would try to force windows to use vertical sync at all times...the NUC oddly uses something around 29Hz as a default refresh rate... I would presume your TV or Receiver uses something around 50 or 60 Hz?
Windows desktop refresh rate is set to 60 Hz non interlaced.
Works all fine apart from what I mentioned (odd artifacts when switching resolutions outside or within Windows 8.1 and frequent display corruption when using applications setting display frequency to match video's) .
Daneel3001, we always recommend customers to use straight connection. In your case, the Pionner receiver is working as an adapter. That could be the reason of the behavior you are getting when it is between the NUC and the TV.
We tried to make as many third party components compatible as possible, but do to the sheer quantity of these third party components we cannot always guarantee compatibility.
Please check the HDMI cable you are using is 1.4a, since this is the only one that support audio and video.
You can also try installing the latest audio driver available for Windows 8.1
Check if you using the latest BIOS version and the latest firmware of the device.
sorry, i dont understand what HDMI 1.4 has to do with this issue. HDMI Cable are transmitting audio and video from the beginning. Does the NUC really needs an special cable just to have audio on a common tv?
I installed the latest graphics drivers you linked and it's still not helped the situation.
I still do get that "noise pattern" showing when changing resolution such as during boot or when I configure some applications to select an alternative frequency to match the one of movies being shown.
I believe the noise pattern seems to show for a little less time than it did before but it might be subjective.
If I remember I had my receiver setup as HDMI passthrough but I will double check that.
Daneel3001, some products are experiencing audio issues related to HDMI. You would be able to find additional information on the following link. The information provided was given by an Intel Engineer.https://communities.intel.com/message/218663#218663
