3. Plug power cable back in and start computer.
4. Navigate to Creative's website, locate your specific product under their support section, then click on downloads. Download the most recent drivers for your specific soundcard and install. Wouldn't be a bad idea to restart after this.
5. You're done! Configure settings using Creative Audio Control Panel (should be in your start folder under Creative, if you installed everything).
You missed a critical thing there bro...
If you just uninstall the drivers for Realtek onboard audio and just reboot it will be re-detected by windows and it will install generic boxed microsoft HD audio drivers and the device will still be active if what your try to do is disable it!!!
You need to enter the BIOS and disable the soundcard AFTER uninstalling the drivers!
I don't see the point in this with windows 7 as the new audio API etc runs fine with multiple soundcards. No reason to uninstall the realtek IMHO as you can assign the expansion audio card to be the default. A big part of Vista/7 is the audio drivers WASAPI and it's ability to use MULTIPLE audio codecs/DSP etc. It was design with the idea that a PC might have say... 4 soundcards. One for the HDMI out on the video adapter, one for say headset, one for speakers and say another DSP for telephony etc. This was one of the main ideas behind the API and why the "Audio Engine" part of it uses Iaudio client "streams" before passing it to the audio engine service. That's above the kernel still unlike XP and back where you'd be at the kernel using kmixer at that point. EEEWWHH!!!
The best part... no more kernel mode driver dev YAY!!!!!!
Vista/Win7 Audio Stack and API
<--32:54 is the best part of the new API IMHO Finally a process/session based volume!!!
Inside Win7 Audio Stack
WASAPI is one of the BEST part of Vista/Win7 and was arguably the biggest change to the Windows ecosystem.Edited by HiroPro - 8/18/11 at 11:00pm
