I just built another HTPC based on the Intel 661 processor. My specs are as follows:
Intel 661 Clarkdale CPU
GIGABYTE GA-H55M-S2H LGA 1156 Intel H55 HDMI Micro ATX
OCZ Gold 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333
2TB Hitachi HD
LG Bluray Drive
Windows 7 x64
My connections are as follows:
Motherboard > HDMI > Denon 4310ci > HDMI > 65" Panasonic HT-65PZ850U
When I install a vanilla copy of Win7 with no other software or drivers the audio works fine. I hear the Win7 startup sound. I get audio in all of my ripped DVDs, etc. I see the correct speaker layout on my Denon display.
As soon as I install the Intel HD Graphics drivers, the audio stops working. I can see the speaker displayed correctly on my Denon. I can see that the computer is making noise through the volume control panel but I get no audio through the speakers. If I go through the generic Win7 speaker config and swith audio profiles from Stereo to Surround (or anything else), the audio starts working again. But once I switch audio sources, ie, Media Player, Media Center, TV, etc...the audio stops working until I switch the speaker config again.
Everything that is recorded has audio but the playback usually requires that I "jiggle" the speaker config to actually hear audio out of my system.
Sometimes I can get the audio to play by switching between an analog channel and a HD channel.
As a side note, bitstreaming with Arcsoft works flawlessly (with the 170 beta build). My Denon decodes DD TrueHD and DTS-HD MA.
As another side note, my old HTPC was connected to the same system but was i7 based with a Xonar 1.3slim audio card. I had zero problems with this setup.
I've setup Win7 from scratch a number of times to isolate the issue to the graphics driver. Everything works fine until I install the Intel driver. I've also tried 3 different versions of the driver to no avail.
As you can imagine, this renders this HTPC pretty useless.
Anyone have any ideas or experiencing the same problems?
Update:
I just installed Win7 x86 and have the same problems. It occasionally DOES work however. So it doesn't look like it's a Windows x64 issue either.
