After a lot of testing i've found out that Intel hdmi drivers have a major bug under windows 8: when you use wasapi (event/push/shared) for audio output and set it to 16/24 bit @ 44000hz the output is SILENT. You get no errors from the application (tested with foobar and xbmc), what you get is a normal playback of the audio file but with no audio output. Can anyone confirm this? In both cases resampling the audio @48khz fixed the issue but still, I/We need also the 44khz. Thank You.
