Hello and welcome to the windows7forums,
Actually, your sound card should appear under Sound, Video and Game Controllers.
Are you using the 32-bit or 64-bit edition and did you try downloading the Windows 7 driver from Realtek's site?
Before installing drivers, try turning off you anti-virus software temporarily.
Also, when the sound lags, right-click on the taskbar, choose task manager and under the processes tab how many processes are running.
Also go to Control Panel > Device Manager and see if NVIDIA nForce PCI System Management has a yellow flags beside it.
Huana,
Did you download the specific driver (and Codec) for the ALC885?
From this site:
Realtek
I've never seen the coprocessor entry, but I'm assumming it's a MAC driver
If everything is working fine, there's no reason to download anything else.
Can you identify the chipset?
It should look something like this:
ALC880/ALC882/ALC883/ALC885/ALC888/ALC260/ALC262/ALC861 HD ...
Try downloading on of these freeware utilities that will grab that info for you
Download System Information Viewer
Download PC WIZARD 2008
Try this:
Go to Start > Rub and type gpedit.msc
2. Enable and Ignore Code signing for drivers policy under User Configuration --->>
Administrative Templates > System > Driver Installation > Code signing for drivers
I was a little confused when I saw your first post stating it was by Nvidia, but then also listed as a Realtek driver.
I found a forum where the members said to locate the Leopard DVD and locate the drivers from that disk in the bootcamp directory there is drivers directory.
Can you locate that CDa nd give it a try?
I have the CD and have located the RealtekSetup.exe -file, installing it now
Ah,
I thought we had it. Did it accept the new driver?
How about the compressor entry, is that still listed in Device Manger with a yellow flag?
What entries in Control Panel Device Manager still have a yellow flag. Is there 1 under Sound, Video, and Game Controllers?
Was the copprosser on the CD also?
