Hi Nic
The problem appear to be specific to Intel HDA driver + new Pioneer SC-LX series of receivers. 44.1khz WASAPI audio only plays when using interlace mode under windows 7 or windows 8. someone in Linux community manage to fix this by modifying the Intel driver (please refer the below link). How can i achieve this under windows7. Any help will be much appreciated.
[Intel-gfx] [Alsa-user] intel-hda: sound via HDMI only when using interlaced modes
Anyone ?!!
