Hello - I have an home built HTPC that will not output surround via the HDMI hooked to my pioneer vsx-920k receiver. Receiver is getting 2 channel (PCM) only. Source provides surround through roku but not directly from the HTPC.
HTPC details as follows: Asus H97M Plus Motherboard, Intel I5/4590/ Windows 7. Asus Motherboard has integrated realtek ALC887 sound processor. No separate video or audio card.
I have updated the drivers, configured the sound options in windows via both the intel driver and realtek driver. Result is the same regardless. Any ideas?
