First Problem i have: (nothing found in Web about this isue)
On Win7 Haswell HDMI audio looses layout (example - center outputs on Rear left and so on). this happens especially after refresh rate change. Only Restarting the PC will help (tried deactivating hdmi audio, replug hdmi, ...).
I have testet this on serveral Mainboards and Processors.
The Problem excists randomly, and is difficult to reproduce.
Second problem:
the well known Silent Stream Bug (on Haswell, Sandy, Ivy). This is a no-go for mediacenter PC (ATI has fixed this isue). When will this be fixed on Intel?
When No Sound played in Windows, a Connected HDMI AMP switches to No Signal.
HDMI should permanent send Silent Audio, otherwise HDMI receivers cannot sync to signal (they dont know if there is 5.1 or 2 channel PCM audio).
Is intel aware of these issues and working on it?
