Have P7P55D and 5.1 sound system connected to it according to user guide (orange+black+lime)
- when booting to Windows 7 x64, all speakers are working properly
- when booting to Windows XP 32bit, only left+right front speakers are working.
VIA HD Audio Deck is configured for 6 channel,
it correctly displays all (orange+black+lime) jacks as "connected",
but test sound is heard only in left+right front speakers
Select the "Speaker Fill" option to get sound from the other speaker. I have this problem in Win 7 64 bit.
I think my problem is from Windows Media Player is only outputting stero signal and i need the Speaker Fill option. If i use the Cyberlink DVD player i get sound out of all speaker without the speaker fill option.
