I don't know if I'm asking this in the right place, but it can't hurt, youz a buncha smart folks here.
I just upgraded. Parts list
Intel Core Quad 9450 stock speed
Asus Rampage Formula 775 X48 Chipset
Using onboard Soundmax extension card
2X HIS ATI 4850's stock speed
4gb Corsair XMS2 Ram 5-5-5-12 (I think)
Vista Ultimate
Now, I'm not a system building noob, everything is updated as far as drivers to the point of 6/29/2008. Any new driver chipset / other that's out, I have.
For HDMI Audio out, I loaded the Realtek 1.96 drivers because that's the only way apparently to get appropriate 5.1/7.1 out from my computer to my 1.3a compatible HDMI receiver. (Thanks for being on the ball with drivers once again ATI...thanks again).
Here is the issue. Even if my receiver is off (device inactive in Sound menu) My DCom and Plug and Play service is eating CPU like mad 20 - 40% use on all 4 cores even though I'm not doing anything. The only way to stop the madness is to go into device manager and disable (or uninstall) the 2 ATI HD Sound devices (under sound). Doing so drops my CPU use to between 0 and 6% on all 4 cores.
Am I the only one seeing this?
I've read in places that this is because of Vista Audio enhancements. I tried disabling enhancements on both sound devices, but even with them disabled I'm getting this obnoxious CPU load.
As a note, This issue also happened when using a Creative Audigy SE 7.1 (instead of onboard sound, I had the extra part, and I tested it in the course of normal troubleshooting).
Please tell me I'm not alone
